[pshaiCmd] Heikin-Ashi prices
stableDescription
Custom command that creates all Heikin-Ashi prices.
And since loops can be slow, you can optimize and set the amount of data you want it to process and output with [dataLimit].
Usage testample (set Price Chart Style to Heikin-Ashi):
-- 0 interval will use current interval, limiting processing to 10 candles
local prices = CC_GetHeikinAshiPrices(0, 10)
Plot(0, 'o', prices.heikinOpen, Blue)
Plot(0, 'h', prices.heikinHigh, Red)
Plot(0, 'l', prices.heikinLow, Green)
Plot(0, 'c', prices.heikinClose, Purple)
