@tomorton I have used the exact same idea years ago and then discarded it

as you can see on paper it looks very good ...but you have to capture 2 grids before becoming profitable..
As the entry condition does not matter the system depends on continuous price trend without retracement by 1g.
the problem is price action very frequently moves/retraces by 1g regardless of what you choose as g.
After a sample number of trades
what I observe is roughly 45% trades are -1g and 25% trades are 0g
so 70% trades end up losers
And 10% trades are 1g which returns 0
rest 20% trades will capture 2g to 7g ...anything beyond is very rare.
and with each additional g the % number of trades will reduce...
