Just one question, how are you calculating your risk/reward ratio... this seems pretty key to the whole thing so more info on this would be great!

Great question Hive account@marcusbraeburn!

The risk-reward ratio is very simply calculated by:

Potential Profit / Potential Loss = Risk/Reward Ratio

For example, using the Belgium O2.5 trade above:
Target price: 8 ticks @ 1.90
Stop-loss: 4 ticks @ 2.02
= 8 / 4 = 2, so 2:1 (for every 1 we risk, we expect a reward of 2, meaning a strike rate of 1 in 3 will allow us to break even as -4 -4 +8 = 0).

Aiming to publish my results post later today :)
