Another tumultuous week with FOMC and NFP and the total win/lose is 6/10 so not bothering to continue this experiment especially as for a system with a 1:1 risk reward ratio the win rate needs to be over 50%.
Now need to think of a new experiment in the quest for a weekly set and forget system. The IV bands worked well for forecasting levels but, as ever, getting the direction right over a weeklong period was the problem.
