Hi Boss

You could open a sell with a very small trade size, then increase the next trade size by 1.5 at every step of 50 pips.
End at 5 trades.
You would have around a 90% chance of ending in profit after factoring in the average price on the way back down.

The only problem is R & R. You will cope a large loss now and again which can cancel out a few good wins.
