Help me convert my EA to trade on all symbols at once

I currently have an EA that performs exactly the way that I want it to but only for a single symbol at a time. Id like to have this converted so that it can trade under the prescribed conditions, but for as many symbols as I attach it to.

high Level explanation of how the EA works:

EA looks at buffers for x number of indicators then places 2 trades if all conditions are met. One trade is set to a Takeprofit of 1x ATR and then there is no TP placed on the second trade so that it just runs. Once the 1st TP is triggered the StopLoss is moved to the trade open price (breakeven stop) then from there enters a trailing stop situation at 1.5x the ATR unit either the trailing stop is hit or the exit indicator conditions are triggered (which is another indicator in use in the program).

1 - Currently, trades are only entered if PositionsTotal()==0, 

2 - Breakeven stop is triggered by PositionsTotal()==1 & StopLoss Price currently less than open price (Long position example)

3 - Further Trailing stop triggered by PositionsTotal()==1 & Stoploss price currently equal to or greater than open price (Long position example)

4 - Exit indicator triggered by reverse of indicator open condition (eg if 1 line of the exit indicator needs to be above another to open a position, when it drops below, the trade positions will close at the beginning of the next bar

All of the above conditions needs to work on every symbol. not just one at a time. 

Happy to discuss anything further if required
