Elite Range Bar System is superb system where you can use M3 TF in your strategy. It is a scalping system and you can do a backtest or use a MT4 simulator to test it. It is possible to easily backtest visually with range bars. Unluckily due to limitations in MT4 itself you can’t actually run a Strategy Tester session properly. An arrangement of visual back-testing and a number of forward chart studies should be all you need though to know the setups and how to be appropriate them in live sessions. You can yet backtest it too with active trading in NinjaTrader and TradeStation.
Personally, I use winning percentage which usually ends up somewhere in the 70-80% range on a monthly base. Individuals who use my system have a wider variety of probable win percentages, but there are fairly a few that do improve than me. The problem with answering this issue is that the Elite Range Bar System is partly optional so the win percentage will depend on an amount of personal factors like experience, personal psychology, pairs traded, and so on.
I am far more discriminating on my CT trades to stay the win rate superior so it depends on what you feel relaxed with and how you concern it.
