Create market order with SL TP in pips, not predefined price

I scalp XAU (gold) in 1 min chart. Into the chart I have placed 3 emas: 9, 20 and 50 and they follow the 5-min chart. When trading I have market order window in MT5 open and I´m ready to hit the button at anytime price action tells me.

There are a major problem setting SL and TP:

- I can only set fixed price in SL and TP. Price moves very quickly so I´m constantly behind. For example let say I want to buy gold at price 3660 and set TP and SL 2 usd from entry. It takes some time to manually enter SL 3558 and TP 3663 and when I´m done the price have already moved  so my entry is no longer valid.

What Would Fix All My Problems:

When I launch "SkalpSkalp" EA it shows clearly seeable window where you can choose following options:

- which pair to trade (dafault Gold)

- lot size

- take profit in dollars

- stop loss on dollars

- buy and sell buttons

For example after I start the program in the window I choose to trade goldand set lot size 0.1. I also set TP SL to three dollars and after that all I need to to is hit either buy or sell button and ea sets SL and TP automatically in 3 dollars part from entry.

I´d also would like to have both ea and source code I can modify myself.
