Imagine that System A has seventy percent winning trades, making thirty pips profit on the wins and losing 40 pips on the losses. System B has 40% winning trades, seventy pips up on the wins and 30 pips down on the losses.
System B will make barely more profit in the long term, but it will generally have runs of many losses in a row. Thus most new traders would do better with system A. Another system that has 85% winning trades, making 20 pips profit on the wins and losing 60 pips on the bad trades, would also make a profit in the long run but just a couple of those 60 pip losses in a row could lead to high stress and bad decision making. You will need to consider what times you are able to be online and trading. If you only have a tiny window of time when you can trade, you might need a system that works well for a particular currency pair that’s active at that point. There may be many factors like this to take under consideration when thinking about forex day trading methodologies dependent on your current position..
