No Sleep EA
It can work on any demo or live account for unlimited period of time.
It also can be back-tested, even I'm not back test believer. Forward test is the best of course.

I made 20% in 15 days with only 6.5% DD on EURUSD ... Can work on any pair. Lately, I use it on Gold because of the high lot rebate I got from broker and it's profit as well.

So, easily can made 40% a month. You can even make more than 100% but you need to withdraw profit frequently.

You can use it on any time frame ...
If you want to use multiple pairs, then use safer settings ...
If you want to use 1 pair, I recommend GBPUSD or Gold but current settings
will not work on gold, you need to use yours to let it go.

Lower time frame means higher profit, higher DD ...
Higher time frame means lower profit, lower DD ...
