MQ5 errors converting MT4 to MT5

Hi I'm trying to convert MT4 EA to MT5 EA.
I'm almost there, when I compile there are errors. Can anyone help me solve this so I can make this work in MT5.

This is Close All Trade Button EA as per https://www.forexfactory.com/thread/...n-on-screen-ea

It's going to take you some work and learning, because the code is significantly different in MQL5, especially trading code. You can't just Close a trade anymore, you have to use TRADE_ACTION_DEAL. Look that up in the editor help and see the example for Closing a trade. Just copy and paste the whole section. You might instead want to modify the simple Close All Trades script that someone posted in that topic you mentioned. Maybe a little easier. I'm trying to do partial closes and it's not working; hopefully someone who knows will reply to my post. Good luck.
