I am planning to take trade logs from a website and push it through Fyers API to my account. I have a small issue regarding Index option contract symbol. As I read in Fyers API docs, I could see that the weekly option contracts have " {Ex}:{Ex_UnderlyingSymbol}{YY}{M}{dd}{Strike}{Opt_Type}" and monthly contracts have "{Ex}:{Ex_UnderlyingSymbol}{YY}{MMM}{Strike}{Opt_Type}" this as symbol input. The issue is that the website provides trades with symbol "date-month-strike". I could convert it for weekly but it would be confusing for monthly. What is the workaround for this?
