I favoured your system by supposing that you get in at the low of the day, which is impossible. So real performance will be even worse then what I calculated.
Almost 92% trades that will not reach 200 points, so no profit.
Your average profit should be 11 times bigger than your average loss, and then you should still deduct commissions, slippage ....
Not really a performing system if you can only guess 8,38% of the time the good direction. Random choosing or gambling will be much better.
If I take as entry (HIGH+LOW)/2, you have almost 95% losers and average profit should be 17 times bigger than average loss, and then you should still deduct commissions, slippage .....
