Get the error code first.

Result.retcode=10013 - Incorrect query

ZeroMemory(request);

This should at least be added and an error in the query, check the data.

Hello Dear Professionals!

I've been longing to try out the "Japanese Candlestick_patterns"(https://www.mql5.com/ru/articles/101),

I think that the indicator should be attached to the Expert Advisor, I tried it and failed.

I can't figure out how to attach it to an EA, I tried it and it didn't work.

I cannot pull out the data from OnCalculate and iCustom() does not work.

Apparently the data is not in buffers and through iCustom, ideally the indicator should be implemented directly in the EA, if you are not qualified for this job ask for a service job, I think someone will do it for 50 credits.

Maybe there is a clear example with placing orders and changing them?

There are plenty of EAs in CodeBase.
