Hi,
I can help with that.
to be honest I didn't work with Sierra chart. but I have a great experience with trading and developed hundreds of bots and indicators for trading on many other platforms like MetaTrader, Ctrader, TOS(thinkorswim), etc.
so if you don't mind contact me to discuss all the other details if there. and let's try work on what you want
for more reference about me, you may have a look at my profile.
Regards,
Amr
