Hi

You are getting that error message by inadvertently  referencing
an array element of -1 by the following code :

previousstoch = stoch[stochcounter - 1];

Ensure stochcounter is greater than zero eitherwise you are referencing
shoch[-1] .You will need to do the same for your other array also.

hello,

can someone help me with this code? I am attempting to spot bullish
divergences between price and stochs. the code successfully collects all the
price lows and the corresponding stochs values, but fails when I try to
compare the current prices and stoch values with the previous ones. I keep
getting a message saying "ther analysis technique is trying to reference
data past the bounds of the array". any idea on how to fix this?

thanks in advance

if date = xxxxxxx {date with bullish divergences}  then begin

Inputs: HighValue(High), LowValue(Low), CloseValue(Close), Length(14);


vars: StartofDay(false),LowestLowSoFarr(0),LowestStoch(0),Kline(0),Dline(0),

currentlow(0),previouslow(0),currentstoch(0),previousstoch(0),counterbis(fal
se),
    PriceCounter(0),StochCounter(0);

array: lows[20](0);
array: stoch[20](0);

Kline = SlowKCustom(HighValue, LowValue, CloseValue, Length);
Dline = SlowDCustom(HighValue, LowValue, CloseValue, Length);
StartofDay = date<>date[1];


currentlow = lows[pricecounter];

    
previouslow = lows[pricecounter - 1];
currentstoch = stoch[stochcounter];
THIS PART IS NOT WORKING

if StartofDay then begin
