I stand corrected. It does produce a signal every high.
My concern though is not with that, it with this part of the code:
Reason= Cross( MACD(12,26), Signal(9) );
for( i = 0; i < BarCount; i++ )
{
if (Reason[i] == True)
{
My understanding is that I should only have a signal if there is a cross of
the MACD and the Signal at the i bar. However, I am producing a signal at
every bar regardless of the cross. That's why I was telling you the issue is
not with the buy statement, but with the if section.
Thanks,
Jerry

Buy is like a light switch ... On or Off, it is NOT a methodology to
take action at a price ...
Buy = H ... Tells AB to Buy on EVERY BAR at the HIGH of that Bar ...
Why ? ... because BUY and H are arrays ...
Although incorrect ... If you had said ... Buy[i] = H[i]; ... The buy
would probably have occured on the bar you wanted it to i.e. the same
one where the cross occured ... but NOT at the High ... For Buys to
occur at specific points you need to use the BuyPrice Array ...
PS ... Buying at the H or L price of the current bar is never a good
idea because these are unknown until the bar is no longer current.
