i've been using chatgpt and i found a few people had similar error but i dont know anything about coding. If someone can help I'd really appreciate this 
 
This originally worked for MT4 but when i used chatgpt to convert it to MT5 i'm getting this line error

search this website for the errors and the function SymbolInfoDouble.

OMG it worked. Thank you so much !! 
 
I ran a strategy tester and i'm getting this error in the journal 

2025.03.16 00:55:25.551 Core 1 2024.07.11 15:42:09   failed market buy 0.1 GBPJPY sl: 3.000 tp: 207.215 [Invalid stops]


any chance you know what could cause this or will it be different when it's in a live trading condition?

do you know how to use search features? on every page of this website there is a search bar.

However, after looking at your code in previous msg, i can see several issues. first will be SymbolInfoDouble is not used appropriately.

 
The “Invalid stops” error means that one or both of the stop loss (SL) and take profit (TP) levels you’re sending do not meet the broker’s requirements.
Recheck the SL/TP and Fix it.

If I knew what I was looking at that yes It would help but i literally don't have anything about coding. I used chatgpt to write these codes. Thank you for your help.
