A few pages back there was talk about shiny object syndrome - that resonated with me as I have been guilty of this too.
There was another post about sharing collective knowledge to make our trading better, so I will share with you my experiences.
My only real success to date, which is still running, is waka waka. The most up-to-date version is available either here or on the old forum.
You need to run a few tweaks to really make it shine. Download the demo MT5 version from MQL website for backtesting, then purchase the MT4 version on clubbingbuy.
To make waka long term success I have made the following tweaks:
Allow trades on same side of currency set to FALSE.
Currencies set to AUDCAD,NZDCAD only.
OPO TP set to true.
With these 3 tweaks alone, waka is a resilient powerhouse. You can run it 0.01 per $US500 and set your account stoploss to 25% drawdown, and sleep easy. Turn holiday trading (over christmas) to OFF. You don't even need to run the news filter...
I am legit running these settings on 2 live accounts with $10k each, and I wish I had just stuck with them. I diverted some profits to side projects that I found on here, and they've all been a massive fail so far.
This experience is my gift to the forum, free of charge
