Ken, if you want to make it believable then you need to tone that down a bit.
If everyday was like Friday we would be all be very rich from trading pretty quick. In fact we don't even need every day to be so easy, jut one day a week like Friday would be.
Last week was quite interesting in that Tues, Thurs and Friday were like free money days. If we can correctly identify such days, even not from the beginning and only trade them accordingly it would be a winning strategy.
The biggest problem facing most traders is firstly the inability to identify that 10% time and secondly lack of patience waiting for it, and lastly the proper execution when it arrives.
If you have proper risk management and discipline you should be profitable. That’s an example of the trading edge, so to speak.
