What is the format to create a constant that change the adjust button? ejm (String, double, etc)

Heiken ashi of fxdreema is the same as heiken ashi of MT4?

Anyone knows a good platform for doing backtesting?

I have created a code in fxdreema, then compiling it into a .mq4 file and then i went to the section "Converter" and created a MQL5 file. But when i copy the new file in the MQL5/ experts file it does not show up when i open the platform.. Anyone has compile codes into MT5???

But how can i install the code as .mq4 file?

I have tried to save my robot but it does not appear in the mt5 screen even if i refresh the folder... what can i do?
