Maybe you should concentrate on only one trading asset (e.g. USDCAD or USDCHF or EURUSD) to prevent yourself from risking too much at once. Also maybe the worst trade should also be lower than the best one. 62% winning rate is already good. I see you often close bad trades like at -50pips but good trades only at +30pips. Maybe with a 62% winning rate it's better to setup both SL/TP to 50pips (higher risk) or 30pips (lower risk), or 50pips SL and 100pips TP. Also the lot-size seems to be sometimes very high. Try it with '1lot for every 100k account-size', so for your account it should be a max. of 3.5lot per trade atm, and not 50lot). At the moment it looks like 'martingale' which will never work out at the end if your SL or TP is too far away from the entry point.
