I created this mql5 project using some MA crossings:
https://fxdreema.com/shared/0cGW7Cuad
I cannot backtest it because I get a weird error mesage saying: Error: Indicator not handled. (handle=-1 | error code=4002). Cannot load indicator 'Moving Average' [4002]
I never had an issie like this. These are the blocks including MA conditions:
I reviewed over and over and I simply can't see what the problem is. Could someone please take a look at it? 
@talalkhan Can you please share the link to your project?
@kestra Then you will need a variable controlling when that happens. You can use an int variable counting how many open trades are right now. If it reaches 3, then a new structure should change the initial lot size to the 0.01.
@julianrob This means your broker doesn't accept any lot size value for XAUUSD. Please check your broker's conditions for that symbol.
@suyirich That logic is wrong. What do you exacty need?
@ecowith This is the way to close them:
I'm not sure what you mean when asking for 'same another condition' to add volume, sorry.
@xlestergg This one is for real coders. Dd you confirm the indicator works correctly when used on the MT4 platform?
@kunalyadav1809 What's the point of waiting for two seconds after the crossing happened? Why not as soon as the crossing happened?
@slimmz Can you please share the link to your project?
@suyirich Where all the other blocks. You selected a vertical line and not a horizontal one. And what criteria are used to plot all those lines?
@tjaart fxDreema is not designed to create indicators, but EAs.
@lanrayy In that case I have no explanation for that behaviousr. I recommend to caontact the admin directly to let him know.
@afika Hi Afika. Welcome to fxDreema. We'll be please to help you.
@traderthomas Can you please share the link to your project?
@maximump The easiest way to do it is creating two variables: one counting open longs and the other for shorts. An then compare both with a normal 'condition' block.
@suleyman-0 If you want to milint tha max amount of open trades then you need to use this block before the 'add to volume' block:
I'm afraidn I don't fully understand the second issue you sated. What do you exactly need?
@khalids222 Yes, I recommend that. Is it not an 'elegant' way to do it, but it is effective. On the other hand, you can create a rigid structure of condition blocks determining your progression. Mostle like in this example I created some time ago based on the 'oscar's grind' strategy. I hope it helps:
