Take ATR value from specific day

Hi fellow traders,

I have a very specific issue to solve - I would like to take the ATR value (measured over 10 day length) from a specific day.

I trade daily bars, Aus Stocks, this is for an ATR Trailing Exit from a long position.

Here is the code (If anyone thinks that this is not a strict trail (ie, only trails up, does not trail down), please let me know. I think I have coded it right but you never know).

 

Code

Inputs: TrailingATRs(4), ATRLength(10); Var: PosHigh(0); Var: ATRVal(0); ATRVal = AvgTrueRange(ATRLength) * TrailingATRs; If MarketPosition = 1 Then Begin If BarsSinceEntry = 0 Then PosHigh = High - ATRVal; If (High - ATRVal) > PosHigh Then PosHigh = High - ATRVal; If High < PosHigh then Sell ( "ATRtrail" ) Next Bar at PosHigh or lower ; End;

The issue is I want ATRval to be taken from the day that the highest high occured. At the moment it does not seem to be doing that.

Thank you in advance for any help!
