Modify trading panel EA to allow multiple trades and SLs

So, I have the attached include and ex files (which I got from online. I cannot remember the time and where though). I would like you to edit it to fit something I have and use in excel.

What I want is that I want to specify these main parameters: 

1. Number of trades (I do not think it should be difficult but If it will be too complex and challenging, then you can set number of trades to just 3). That is fine

2. Total Amount I want to lose across all the trades combined. So, if I specify $200, I will want to lose a total of $200 should all the trades go against me.

3. A lot size. (If making this fixed or variable will make it easier for you, that is fine. Define it whichever way you believe will make it easier for you and work best)

4. You can define  a fixed TP level for all trades, that is fine. so far as I can drag them, I will just drag and manage them manually

Given the specific Lot size, the EA will calculate the distances for all the number of trades and their SL and TP prices and set the lines there. So, when comfortable, I select a buy/sell/stop or whatever and it goes ahead and place the trades. As you can see the EA is doing this for only 1 price level, so I want it modified to account for a variable (specified) number of trades. 

Please note: There is a similar tool here, for inspiration if that helps: https://www.mql5.com/en/market/product/112514?source=External#description

Also note that, it could be you already have the code or a panel design that you want to use, I am fine and not particular about the panel, design etc. so far as it looks professionally designed and pleasant, and does the job, that is fine by me 😊

Any questions, please do let me know and I will do my best to explain.

Thank you
