Overview

Technical indicators are mathematical calculations applied to a security's price and/or volume to forecast future price movements and identify trading opportunities. The indicator APIs on this page return server-computed values for direct consumption, while formulas are included to explain the math behind each model. Every indicator still originates from OHLCV candle data returned by market data endpoints such as /api/v1/history endpoint — no third-party libraries required.

📊Trend-following

SMA & EMA smooth noise and reveal the underlying price direction.

🔀Momentum

MACD captures the strength and direction of a trend's acceleration.

📏Oscillators

RSI measures the speed of price changes to spot exhaustion zones.

🔗Composable

Chain indicators together for confluence — or use the Sentiment API for a ready-made composite RSI + MACD + EMA score.

⚠ Important: Technical indicators are derived from past price data and are not predictive on their own. Always combine them with proper risk management, context, and multiple confirmations before executing trades.

Simple Moving AverageSMA

Trend-following · Lagging

The Simple Moving Average computes the arithmetic mean of closing prices over a rolling window of n periods. It is the foundational building block of nearly every other indicator. The longer the period, the smoother — but laggier — the output.

Formula

SMA(n, t) = ( Close[t] + Close[t-1] + ... + Close[t-n+1] ) / n

API Endpoint

GET /api/v1/indicator/sma?apiKey=YOUR_API_KEY&SymbolCode=AAPL&TimeFrame=H1&Period=20

Common Periods

Period	Timeframe	Typical Use-Case
10	M15 / H1	Short-term momentum, scalp entries
20	H1 / H4	Intermediate trend & pullback zones
50	H4 / D1	Medium-term trend direction
100	D1	Major trend, institutional reference
200	D1	Long-term bull/bear market threshold

Signal Interpretation

bullishPrice crosses above SMA → potential uptrend start or pullback entry

bearishPrice crosses below SMA → potential downtrend or overhead resistance

bullishSMA-50 crosses above SMA-200 (Golden Cross) → strong long-term bull signal

bearishSMA-50 crosses below SMA-200 (Death Cross) → strong long-term bear signal

neutralPrice oscillating around SMA → choppy / range-bound market

Exponential Moving AverageEMA

Trend-following · Lagging · Weighted

The Exponential Moving Average applies a multiplier that gives more weight to recent prices, making it react faster to price changes than an SMA of the same length. Widely used for crossover signals, dynamic support, and as an input to MACD.

Formula

k = 2 / (n + 1) EMA[t] = Close[t] × k + EMA[t-1] × (1 - k)

Tip: Always seed the EMA with an SMA of the same period on the first bar — the API handles this automatically so you receive stable values from the very first candle.

API Endpoint

GET /api/v1/indicator/ema?apiKey=YOUR_API_KEY&SymbolCode=AAPL&TimeFrame=H1&Period=20

Common Periods & Multipliers

Period	Multiplier (k)	Typical Use-Case
9	0.200	Short-term signals, scalp/swing triggers
12	0.154	MACD fast line
21	0.095	Crypto & equity swing entries
26	0.074	MACD slow line
50	0.039	Medium-trend filter & dynamic S/R
200	0.010	Long-term trend, institutional benchmark

Signal Interpretation

bullishPrice crosses above EMA → momentum shift to the upside

bearishPrice crosses below EMA → momentum shift to the downside

bullishShort EMA crosses above long EMA (e.g. EMA-9 > EMA-21) → trend acceleration up

bearishShort EMA crosses below long EMA → trend acceleration down

neutralEMA slope flattening → trend losing momentum, potential reversal zone

Weighted Moving AverageWMA

Trend-following · Lagging · Linearly weighted

The Weighted Moving Average assigns linearly increasing weights to closing prices so that more recent candles have a greater impact on the result than older ones. WMA reacts faster than SMA but produces smoother output than EMA on sharp spikes — making it a useful middle-ground for trend-following strategies.

Formula

WMA = Σ(Close[i] × Weight[i]) / Σ(Weights) Weight = period, period-1, ..., 2, 1 (newest → oldest) Σ(Weights) = period × (period + 1) / 2

Note: WMA reacts faster than SMA but smoother than EMA on sharp spikes. Use it when you want recency bias without EMA's exponential tail.

Relative Strength IndexRSI

Momentum · Oscillator · 0–100 scale

The Relative Strength Index measures the speed and magnitude of recent price changes on a 0–100 scale. Originally developed by J. Welles Wilder, it is one of the most-used oscillators for identifying overbought and oversold conditions.

Formula

RS = Average Gain (n) / Average Loss (n) RSI = 100 − 100 / (1 + RS)

API Endpoint

GET /api/v1/indicator/rsi?apiKey=YOUR_API_KEY&SymbolCode=AAPL&TimeFrame=H1&Period=14

RSI Zones

RSI Range	Zone	Interpretation
> 70	Overbought	Potential reversal down or pullback
50 – 70	Bullish	Upward momentum, trend continuation
45 – 55	Neutral	Indecision, range-bound
30 – 50	Bearish	Downward momentum, trend continuation
< 30	Oversold	Potential reversal up or bounce

Signal Interpretation

bearishRSI above 70 → overbought; watch for reversal or pullback confirmation

bullishRSI below 30 → oversold; watch for reversal or bounce confirmation

bullishRSI crosses above 50 → momentum turning bullish

bearishRSI crosses below 50 → momentum turning bearish

bullishBullish divergence (price lower low, RSI higher low) → potential trend reversal up

bearishBearish divergence (price higher high, RSI lower high) → potential trend reversal down

neutralRSI oscillating around 50 without extremes → consolidation / no trend

Bollinger BandsBB

Volatility · Bands: Upper · Middle · Lower · Requires Pro+

Developed by John Bollinger in the 1980s, Bollinger Bands place a volatility envelope above and below a simple moving average. The bands widen during high volatility and contract during low volatility, making them ideal for identifying breakouts, squeezes, and overbought/oversold conditions within a trend.

Formula

Middle = SMA(Close, n) σ = Standard Deviation of Close over n periods Upper = Middle + (k × σ) Lower = Middle − (k × σ) Default: n = 20, k = 2

API Endpoint

GET /api/v1/indicator/bollinger-bands?apiKey=YOUR_API_KEY&SymbolCode=EURUSD&TimeFrame=H1&Period=20&Multiplier=2

Parameters

Param	Type	Default	Range
period	int	20	2–500
multiplier	decimal	2	0.1–10

Signal Interpretation

bearishPrice touches or crosses above the upper band — overbought; momentum may be exhausting

bullishPrice touches or crosses below the lower band — oversold; potential bounce or reversal zone

neutralBands narrow (squeeze) → low volatility consolidation; precedes an imminent breakout

bullishPrice breaks above the upper band after a squeeze with rising volume → bullish breakout

bearishPrice breaks below the lower band after a squeeze → bearish breakdown

neutralMiddle band (SMA-20) acts as dynamic support in uptrends and dynamic resistance in downtrends

Stochastic Oscillator%K / %D

Momentum oscillator · Range: 0 – 100 · Requires Pro+

Developed by George Lane, Stochastic compares a closing price to its price range over a given period. It produces two lines — the fast %K and the slower signal line %D — used together to identify overbought/oversold conditions and momentum crossover signals.

Formula

%K = 100 × (Close − Lowest Low(K)) / (Highest High(K) − Lowest Low(K)) %D = SMA(%K, D) -- signal line (smoothed %K) Default: K = 14, D = 3

API Endpoint

GET /api/v1/indicator/stochastic?apiKey=YOUR_API_KEY&SymbolCode=EURUSD&TimeFrame=H1&KPeriod=14&DPeriod=3

Stochastic Zones

%K / %D Value	Zone	Action
> 80	Overbought	Consider reducing longs or watching for %K/%D bearish cross
< 20	Oversold	Consider longs or watch for %K/%D bullish cross
50	Midline	Strength above 50 = bullish bias; below 50 = bearish bias

Signal Interpretation

bullish%K crosses above %D in oversold zone (< 20) → strong buy signal

bearish%K crosses below %D in overbought zone (> 80) → strong sell signal

bullishBullish divergence: price makes new low but Stochastic doesn't → hidden strength

bearishBearish divergence: price makes new high but Stochastic doesn't → hidden weakness

neutralBoth lines hovering in 40–60 range → no clear directional conviction

ATR

Average True RangeATR

Volatility · Stop-loss sizing · Requires Pro+

Introduced by J. Welles Wilder Jr., ATR measures market volatility by computing the average of the True Range over a given period. It does not indicate direction — only how much price is moving. ATR is the industry-standard tool for placing stops and sizing positions proportional to current market conditions.

Formula

True Range (TR) = max( High[t] − Low[t], |High[t] − Close[t-1]|, |Low[t] − Close[t-1]| ) ATR[0] = SMA(TR, n) -- seed with simple average ATR[t] = (ATR[t-1] × (n-1) + TR[t]) / n -- Wilder smoothing Default: n = 14

API Endpoint

GET /api/v1/indicator/atr?apiKey=YOUR_API_KEY&SymbolCode=EURUSD&TimeFrame=H1&Period=14

Practical use: A common stop-loss rule is 2 × ATR below entry for longs and 2 × ATR above entry for shorts. This keeps stops proportional to actual market noise and reduces the chance of being stopped out by random fluctuations.

Signal Interpretation

neutralRising ATR → volatility expanding; expect larger swings, widen stops accordingly

neutralFalling ATR → volatility contracting; typical of consolidation before a breakout

bearishVolatility spike on a bearish move → sellers panicking; trend may accelerate downward

bullishATR spike on a breakout above resistance with bullish candle → high-conviction move

neutralATR near multi-week low → Bollinger Band squeeze likely forming; watch for breakout setup

CCI

Commodity Channel IndexCCI

Overbought/Oversold oscillator · Unbounded · Requires Pro+

Developed by Donald Lambert, CCI measures how far the current Typical Price has deviated from its average over a rolling window, normalized by mean absolute deviation. Unlike RSI and Stochastic, CCI is unbounded — it can go well beyond ±100 during strong trends, making it useful for both overbought/oversold detection and trend strength.

Formula

Typical Price (TP) = (High + Low + Close) / 3 SMA_TP = SMA(TP, n) Mean Dev = (1/n) × Σ|TP[i] − SMA_TP| for i in [t-n+1, t] CCI = (TP − SMA_TP) / (0.015 × Mean Dev) Default: n = 20

API Endpoint

GET /api/v1/indicator/cci?apiKey=YOUR_API_KEY&SymbolCode=XAUUSD&TimeFrame=H1&Period=20

CCI Zones

CCI Value	Zone	Interpretation
> +200	Extreme overbought	Very rare; strong upward momentum; possible reversal warning
+100 to +200	Overbought	Upward breakout zone; trend may continue but stretched
-100 to +100	Neutral	Normal range; no extreme signal; watch for direction
-200 to -100	Oversold	Downward breakout zone; trend may continue but stretched
< -200	Extreme oversold	Very rare; panic selling; possible bounce or capitulation

Signal Interpretation

bullishCCI crosses above +100 from below → bullish breakout signal; price above its mean

bearishCCI crosses below -100 from above → bearish breakdown signal; price below its mean

bullishCCI returns above -100 after being oversold → potential reversal buy entry

bearishCCI returns below +100 after being overbought → potential reversal sell entry

neutralCCI divergence from price (like RSI) signals trend weakening ahead of reversal

Williams %R%R

Momentum oscillator · Range: -100 to 0 · Requires Pro+

Developed by Larry Williams, Williams %R is an inverted momentum oscillator that measures the current closing price relative to the high-low range over a lookback period. It oscillates between -100 and 0, making overbought/oversold zones the opposite of most oscillators.

Formula

Highest High = max(High[i]) for i in [t - n + 1, t] Lowest Low = min(Low[i]) for i in [t - n + 1, t] %R = −100 × (Highest High − Close) / (Highest High − Lowest Low) Range: −100 (extreme oversold) to 0 (extreme overbought) Default: n = 14

API Endpoint

GET /api/v1/indicator/williams-r?apiKey=YOUR_API_KEY&SymbolCode=XAUUSD&TimeFrame=H1&Period=14

%R Zones

%R Value	Zone	Interpretation
0 to −20	Overbought	Price near the recent high; bulls in control but stretched
−20 to −80	Neutral	No extreme signal
−80 to −100	Oversold	Price near the recent low; bears in control but stretched

Signal Interpretation

bearish%R rises above -20 → overbought territory; possible reversal or slow-down ahead

bullish%R falls below -80 → oversold territory; possible reversal or bounce zone

bullish%R crosses from below -80 up through -80 → early reversal signal; confirms oversold exit

bearish%R crosses from above -20 down through -20 → early reversal signal; confirms overbought exit

neutralCombine with EMA direction: oversold %R + price above EMA = higher-probability long setup

ADX

Average Directional IndexADX · +DI · −DI

Trend strength · Non-directional · Requires Pro+

Also developed by J. Welles Wilder Jr., ADX quantifies the strength of a trend without indicating its direction. It is always plotted with two directional lines — +DI (positive directional indicator) and −DI (negative directional indicator) — from which both trend strength and direction can be inferred together.

Formula

+DM = max(High[t] − High[t-1], 0) if > −DM, else 0 −DM = max(Low[t-1] − Low[t], 0) if > +DM, else 0 Smoothed using Wilder's method over n periods: +DI = 100 × Smooth(+DM) / ATR(n) −DI = 100 × Smooth(−DM) / ATR(n) DX = 100 × |+DI − −DI| / (+DI + −DI) ADX = Wilder's smoothed average of DX over n periods Default: n = 14 Range: 0–100

API Endpoint

GET /api/v1/indicator/adx?apiKey=YOUR_API_KEY&SymbolCode=XAUUSD&TimeFrame=H1&Period=14

ADX Strength Levels

ADX Value	Trend Strength	Strategy Implication
< 20	Absent / Weak	Range-bound; prefer mean-reversion strategies
20–25	Forming	Trend beginning; watch for confirmation before entering
25–50	Strong trend	Trend-following strategies perform well
50–75	Very strong	E.g. news-driven move; ride with tight trailing stops
> 75	Extremely strong	Very rare; expect eventual exhaustion / reversal

Signal Interpretation

bullishADX > 25 AND +DI > −DI → confirmed bullish trend — bias long

bearishADX > 25 AND −DI > +DI → confirmed bearish trend — bias short

bullish+DI crosses above −DI while ADX is rising → bullish directional crossover with strengthening trend

bearish−DI crosses above +DI while ADX is rising → bearish directional crossover with strengthening trend

neutralADX < 20 regardless of DI position → avoid trend-following; use RSI/Stochastic for range trading

neutralADX peaks and turns down → trend exhausting; consider tightening trailing stops

Fibonacci RetracementFibonacci

Retracement levels · Support/Resistance · Requires Pro+

Fibonacci retracement levels are horizontal lines that indicate where support and resistance are likely to occur. They are based on Fibonacci numbers and are used to identify potential reversal points. The levels are calculated by taking the high and low points of a trend and dividing the vertical distance by the key Fibonacci ratios.

Formula

// Identify swing high and swing low over the lookback period High = max(High[i]) for i in [t - lookback, t] Low = min(Low[i]) for i in [t - lookback, t] // Calculate retracement levels Range = High - Low Fib_0.236 = High - (Range * 0.236) Fib_0.382 = High - (Range * 0.382) Fib_0.500 = High - (Range * 0.500) Fib_0.618 = High - (Range * 0.618) Fib_0.786 = High - (Range * 0.786)

0.236	23.6%	Minor retracement level, often acts as support in uptrends
0.382	38.2%	Common retracement level, confluence with other indicators
0.500	50.0%	Midpoint, psychological level, often strong resistance/support
0.618	61.8%	Golden ratio, major retracement level
0.786	78.6%	Deep retracement, potential reversal zone

Signal Interpretation

bullishPrice bounces off Fibonacci level in downtrend — potential reversal

bearishPrice rejects Fibonacci level in uptrend — potential reversal

neutralMultiple levels confluence — stronger signal when levels cluster

bullishFibonacci level coincides with support & resistance — high probability setup

neutralLookback parameter controls swing size — larger lookback for major trends

Code Example

fibonacci.js

const BASE      = "https://api.realmarketapi.com"
const API_KEY   = "YOUR_API_KEY"
const LOOKBACK  = 50  // Optional: periods to look back for high/low

Support & ResistanceServer-computed API

Price structure · Key levels · Requires Pro+

The Support & Resistance endpoint returns server-computed key price levels directly. Like the SMA/EMA/RSI/MACD indicator APIs, it analyses historical candle data to identify price zones where buyers (support) or sellers (resistance) have repeatedly stepped in, ranked by touch count.

🟢Support

A price floor. Bulls have historically defended this level. The higher the touch count, the stronger the zone.

🔴Resistance

A price ceiling. Bears have historically sold at or near this level. Multiple rejections = strong resistance.

📊Touch Count

How many times price has tested a level. Higher counts indicate institutional memory and greater reliability.

⏰Last Touched

Recency matters. A level tested last week is more relevant than one tested 6 months ago.

Signal Interpretation

bullishPrice approaching a support level with high TouchCount — potential bounce zone; look for bullish confirmation candles

bearishPrice approaching a resistance level with high TouchCount — potential reversal zone; consider tightening stops on longs

bullishPrice closes above a resistance level — resistance has been broken and may now act as new support

bearishPrice closes below a support level — support has been broken and may now act as new resistance

neutralLevels with low TouchCount (1–2) are weaker and less reliable — use only with strong additional confluence

neutralCombine SR levels with RSI (overbought/oversold) and EMA slope for high-probability entries

Code Example

support-resistance.js

const res = await fetch(
  "https://api.realmarketapi.com/api/v1/indicator/support-resistance?apiKey=YOUR_API_KEY&symbolCode=XAUUSD&timeFrame=H1"

Market SentimentFear & Greed

Composite indicator · RSI(14) · MACD(12,26,9) · EMA-50/100 · Requires Pro+

The Market Sentiment endpoint aggregates multiple technical indicators into a single, human-readable composite score. It combines RSI (14-period), MACD histogram (12/26/9), and the relationship between EMA-50 and EMA-100 to produce a Fear & Greed score (0–100), a sentiment label, and a trend classification — all server-computed in a single API call.

Composite Formula

// Inputs RSI_14 = RSI with period = 14 MACD_Histogram = MACD line − Signal line (fast=12, slow=26, signal=9) EMA_50 = EMA with period = 50 EMA_100 = EMA with period = 100 // Fear & Greed Score (0 = Extreme Fear · 100 = Extreme Greed) FearGreedScore = weighted_composite(RSI_14, MACD_Histogram, EMA_50, EMA_100) // Trend Classification StrongUptrend → currentClose > EMA_50 > EMA_100 AND MACD_Histogram > 0 Uptrend → currentClose > EMA_50 > EMA_100 Sideways → |EMA_50 − EMA_100| ≈ 0 Downtrend → currentClose < EMA_50 < EMA_100 StrongDowntrend → currentClose < EMA_50 < EMA_100 AND MACD_Histogram < 0

API Endpoint

Fear & Greed Zones

Score	Sentiment	Interpretation
0–20	ExtremeFear	Market is extremely fearful — potential contrarian buy zone
21–39	Fear	Bearish sentiment dominates — caution advised on new long positions
40–59	Neutral	Balanced market conditions — wait for directional confirmation
60–79	Greed	Bullish sentiment rising — trend-following strategies in favour
80–100	ExtremeGreed	Market may be overextended — tighten risk management

Signal Interpretation

bullishfearGreedScore rises above 60 → Greed zone entered; bullish momentum building — favour long setups

bearishfearGreedScore falls below 40 → Fear zone; risk-off pressure increasing — reduce long exposure

bullishtrend = StrongUptrend AND fearGreedScore 60–79 → strong directional confluence — high-confidence long bias

bearishtrend = StrongDowntrend AND fearGreedScore 21–39 → strong bearish confluence — avoid longs, look for shorts

neutralSideways trend with Neutral sentiment (40–59) → range-bound conditions — mean-reversion over trend-following

bullishema50 > ema100 AND macdHistogram > 0 → dual EMA alignment with positive momentum confirms bullish bias

bearishema50 < ema100 AND macdHistogram < 0 → dual EMA alignment with negative momentum confirms bearish bias

Combining Indicators

No single indicator is reliable enough to trade in isolation. Effective strategies stack multiple indicators from different categories — trend, momentum, and oscillator — to get confluent signals that dramatically improve signal quality.

🔗

EMA + RSI — Trend Continuation

1Filter direction: price above EMA-50 = only look for longs
2Wait for RSI to dip into 40–50 (pullback without going oversold)
3Enter when RSI starts rising back above 50
4Stop below EMA-50; target previous high

🔀

MACD + RSI — Reversal Entry

1Identify RSI < 30 (oversold) or RSI > 70 (overbought)
2Wait for MACD histogram to start shrinking (momentum fading)
3Enter on MACD line × Signal line crossover
4Tight stop beyond the recent swing; RSI returning to 50 as target zone

✖

SMA Golden/Death Cross

1Plot SMA-50 and SMA-200 on D1 timeframe
2Golden Cross (50 > 200): long-term bull — buy dips above SMA-50
3Death Cross (50 < 200): long-term bear — sell rallies below SMA-50
4Confirm regime shift with MACD above/below zero

📐

MACD Divergence + EMA Slope

1Observe price making new lows while MACD histogram shrinks (bullish divergence)
2Confirm EMA-20 slope is flattening or turning up
3Enter on EMA-9/21 bullish crossover for timing
4Invalidate if price breaks the previous swing low
