Tralling EA for current profit using percentages

I need trailing EA that trails on current profit using percentages. First trade should have dollar amount stop loss. If first trade goes into profit for lets say $10 and I have set the trailing to be 50% of current profit then $5 will be locked, then I open second trade and it goes into profit and both trades are at 20 profit then trailing should be locked at $10. This trailing should add all orders on the account. I first trade is locked at $5 and I open a second trade and price goes back down to profit of $5 then all trades should be closed. EA should display on side. Current locked in profit, current profit etc....This EA has to work on indexes and crypto and forex.

This EA has to trail all trades and obey the stop loss no matter how many trades I add.  If there are 2 trades open and profit is trailing and then I open additional trades EA must still take profit at the same level of trail higher.  This is not an individual trade EA each trade must recalculate the current profit after each trade is added.

Trail All on/off if off trailing will only work on current currency/index

Stop loss:

Brake even After profit: All trades must be closed at no less then this price if in profit x amout

Start Tralling by percentage after X profit reached:

trail percentage of current profit profit:
