@mayfair21 you have to make sure the system takes the qqe. There are so many versions of it and I have tried and it will not accept most of them. Are you able to use the buffers on it? The journal will tell you if if has an error.
For the EA indicators are only numeric values. Bollinger is similar to MA, so it is possible to cross them or anything else that you can do between two MAs or two Bollingers
You want to open 5 orders at the same time or 5 pending orders at different places?
Here are some basic examples https://fxdreema.com/examples
Look at "Buy pending orders in grid" and "Sell pending orders in grid" for multiple pending orders at once.
