Adjustment on existing EA

Hi all,

I currently have an existing EA that I want to have modified. The EA currently works in this way: 

- It reads emails (using Python) and opens trades received from the emails. The email currently looks like this: BUY EURUSD tp=1.057000 sl=1.053500

- The EA then calculates the risk % based on the distance between the SL and current price, and opens the trade in the correct lot size. 

- There is also a 'Martingale' section that can be used to increase the risk % for the next trade after a trade closes in a loss. 

==> All this is working fine. But I want to use the EA in a different way in the future, therefor it needs the following modifications:

- In the future I will send signals like this: BUY EURUSD (without sl/tp behind it)

- The placement of SL should now be calculated on the lowest/highest price of the last x bar(s) + additional margin

- risk % should still be based on the SL/current price

- the EA should check if the last bar closed bullish (in case of BUY signal) or bearish (in case of sell signal), if not the trade gets ignored. 

- the EA should also check some other settings from the last bar (including total bar size, wick size,...) to filter out opening bad trades

- A time filter should be added (only accept signals between certain hours) 

- A spread filter should be added (only accept signals when spread is below x pips) 

- A martingale mode SUM should be added. instead of doubling the risk (1%,2%,4%,8%...) after a loss trade it should also become possible to increase risk by sum (1%,2%,3%,4%..)

- A "Start Martingale after x losses" parameter should be added

- A 'SL to Break Even' function should be added

- A TP selection mode (Pips, RR, Trailing STop) should be added

The Requirements specs (mentioning more detail about what is described above) are available upon request.
