高度激进的网格交易 (Highly Aggressive Grid Trading)

I've been considering/backtesting the idea of a very aggressive grid trading system, although the idea is so simple that I don't know if it really qualifies as a "system". The idea is to start with a 100 EMA and use that as your guide whether to trade long or short. I am testing on EUR/USD on 15M chart. At NY Open, if price is trading below the 100 EMA (and the EMA is not flat) then we are placing sell stop orders at every "zero level" and take profits at every "5 level". Buy stop orders if above the 100 EMA... The highly aggressive part is that there is no stop loss and one bad trade will wipe you out.

Obviously, two factors will have to be in play: 1) starting with an amount of money that is small and somewhat insignificant to you (could be $500, could be $100) and 2) withdrawing money after a set number of consecutive wins so as to not lose everything when the eventual loser rears its ugly head.

To make it worth it - one winning trade would be 10%, so if starting with $500 then you would risk 1 lot and profit $50 off of 5 pips. If disaster strikes, then you would have 50 pips of SL before you are wiped out. After 8 succesful trades you will double your starting amount and at that point could withdraw, say 25% ($250) and then start the process again with the remaining $750 or so, incrementally increasing after each withdraw period.

I backtested this to 96% win rate over the last 3 months within the hours of 8am-12pm EST (avoiding trading during red news of course). The question is - is it profitable over the long run?
