Buy Profitable EA, any kind of strategy is acceptable

I want to buy proven profitable EA, any kind of strategy is considerable, working on any forex pairs or XAUUSD.
I don't want to build from the scratch, so only apply if you already have profitable EA.
Please send your EX4 file in advance with your application (MANDATORY), with additional information as below :
- Pair and timeframe to use, minimum initial capital requirement, and so on
- Type of EA (scalping, in day trading, swing trading, hedging, grid trading, one shoot trading, with/without SL TP, and any other useful information as much as possible)
- Type of strategy (trend following, breakout, trend reversal, anti trend, or whatever)
- Briefly describe how your EA works (this is very important, should clearly explained)
- setting already set to the best setting for the pair (you can describe any other setting if the EA is multicurrency)
- Back testing result (if any)
- Any other information to describe your EA well, more is better

I will do back test based on your EA4 file and complete information, and also will do around 10 days forward trading on demo account with standard spread (not low spread) if back testing result is considered good.
After around 10 days demo, we can negotiate the price based on profit, DD, and other statistical result (if the result is good). I will separately contact you then.

Please don't wasting your and my time by sending bad EA, because I will reject them after back testing.

I can buy more than one EA. As long as I consider the EA is good enough, I will start to negotiate the price. So, more than one developer with good EA have a chance to get bought.

Once negotiation finished with agreed price, you need to send source code of EA (mq4) upon final payment
