1) set up the main chart to be a normal candle chart
2) use this indicator script to plot a secondary window with indicator looks exactly like a HA-chart
3) to use the HA-candle's open/close/high/low value to calculate whatever indicator you want (you may need to create a separate script if you want to plot this indicator in a separate indicator window)

//@version=2 // Note: // if you only want to see the Heikin Ashi Candle but not the normal Candle, // change the overlay option to overlay=true, then hide the normal Candle study("I_Heikin Ashi Candle", shorttitle="I_HA Candle", overlay=false) // --------------- Calculating HA Candle's values // -- you can use either one of the methods below, they give the same values // Method 1 - calculate the HA candle's value by formula haclose = (open + high + low + close) / 4 haopen = na(haopen) ? (open + close) / 2 : (haopen + haclose) / 2 hahigh = max(high, max(haopen, haclose)) halow = min(low, min(haopen, haclose)) // Method 2 - calculate the HA candle's value by pine script function heikinashi() // haclose = security(heikinashi(tickerid), period, close) // haopen = security(heikinashi(tickerid), period, open) // hahigh = security(heikinashi(tickerid), period, high) // halow = security(heikinashi(tickerid), period, low) // --------------- Using HA Candle's values to define indicators // then use the haclose, haopen, hahigh, halow to calculate whatever indicators you want: // e.g. // 1. stochastic // k = sma(stoch(haclose, hahigh, halow, 14), 3) // d = sma(k, 3) // 2. sma // sma14 = sma(haclose, 14) // 3. ema // ema14 = ema(haclose, 14) // --------------- Plotting plotcandle(haopen, hahigh, halow, haclose, title='Heikin-Ashi', color=(haopen < haclose) ? green : red, wickcolor=gray) // END
But I think it may be a problem with TV plotting... I wrote and rewrote a script several times checking multiple sources but the data never matches exactly what's displayed by TV.
To compare them you need to open two chart window, one using TV HA chart and one using a normal chart and generating the HA chart using the script. Hope it makes sense.
