Modifying a trailing stop EA by changing its unit + filter by symbol

I already have an EA that I asked someone to write for me. The EA is a type of trailing stop. It currently calculates profit and losses, setting TP and SL based on $ profits. I would like to change the unit of measurement into PIPS instead of using $. For how pips are calculated please see my attachment. 1 pip is essentially the second last digit of any symbol.

In addition, I would like a feature that filters by symbols (e.g. GBPUSD, EURUSD etc) - currently I load onto each chart, would be nice to specify which symbol(s) the EA is applied to. If I don't specify any filtering by symbol, then default should be based on the symbol of the chart to which the EA is loaded. Also please construct a table that shows the different SL/TP applied to different symbols. Currently my EA displays the target TP and SL for just one symbol. If there are multiple symbols, please show the target for each with a table.
