Heiken ashi custom column counter

I moved your question out of the "Stock Scanners" topic and into the "Watchlist" topic since your request has nothing to do with scanning for stocks.

The following section of code will compute the counts as you have requested:

def haClose = ohlc4;
def haOpen = if haOpen[1] == 0 then haClose[1] else (haOpen[1] + haClose[1]) / 2;
def greenCandle = haClose > haOpen;
def redCandle = haClose < haOpen;
rec countGreen = if greenCandle and redCandle[1] then 1 else if greenCandle and countGreen[1] > 0 then countGreen[1] + 1 else 0;
rec countRed = if redCandle and greenCandle[1] then -1 else if redCandle and countRed[1] < 0 then countRed[1] - 1 else 0;
plot data = if countGreen > AbsValue(countRed) then countGreen else countRed;
