I should have added one too

, keep on posting!!
On a breakout with R:R 1 (TP) :2 (SL) , I would need to win at least 66.67% of my trades to break even. Win rates are currently in the range 80 ~ 85% so my edge would be
85% - 66.67% = 18.33% Edge.
Example Calculation
If I enter 200 trades a year and risk £10,000 to make £5,000 on each trade, the run rate return should be:
[5,000 * (200 * 0.85)] - [10,000*(200*0.15)] = 850,000 - 300,000 = 550,000
Assuming 10,000 is 2.5% of my account balance (400,000), then the annual growth should be 550,000/400,000 = 1.375 assuming no withdrawals. And from there i can calculate the sharp ratio.
