Can you please add a setting so that this EA limits the max number of open positions that have a particular magic number? This would provide more flexibility, so that the user can limit the max open positions from a specific EA, but not limit the max open positions from a different EA or manual trading.

Also a limit on trade volume. What if setting is 2 trades. This is almost meaningless. Lets use example, ea is running and by mistake decimal issue so instead of 0.1 lots the ea opens 1 lot. This is one position, by this current ea this is within restriction. However this is 10x the risk.

So its about volume, amount of open positions and thirdly volume in total.

There is also issue here, lets use example, if set 0.8 lots as max. And ea or manual trading opens 4 positions fx 0.1 thats total 0.4 but oil tries to open 1.4 this wont be allowed as beyond 0.8 threshold. Well the issue is the value per pip varies with all brokers, so it should allow the oil but not more than 8x fx positions. In some cases s&p would be 3.0 yet its value for say 100 pip would be small. The actual trade size is meaningless, its more complex. And so trade size per product should be limit. Furthermore, if the trade is opened and the ea you develop wants to close it after being opened, this could continue in a loop, and spread cost would in a matter of hours wipe the account. If say an ea was attempting to open a trade, restriction was in place, and so ea would open then this ea would close it, and so the loop repeats until a person gets involved. Really this is not ideal needs to prevent the trade from opening in the first place, is this possible?

Input for all products allowed to trade, positions per product, trade size per product, amount of total positions, amount of total trade size

This would be a long list of inputs, but this is pro job.
