Dear David,
I’ve made a stab at it, but problems
remain, eg, there are excess buy and sell signals. Would anyone care to
lend a hand here? My looping abilities are pretty meager and I’ve
likely made a hash of it.
Regards,
Fred

StopLevel =

ProfitTarget = ValueWhen(Buy,BuyPrice*(1+ProfitLevel));
trailARRAY = Null;
trailstop = 0;
priceatbuy = 0;
highsincebuy = 0;
for( i = 1; i < BarCount;
i++ )
{
if( Buy[i] )

priceatbuy

if( priceatbuy > 0 )

highsincebuy

if( highsincebuy >= (1 +

Initiating Trailing Stop after hitting Profit Target

You mean that KB article is not ready to use copy-paste code for your specific
request?
No it isn't. It is not supposed to be.
It was written well before you asked the question. But it is on related stuff.
It is just an example on how to do that on your own.

Yes exactly - add few lines and you will be done.
