Separate lot co-efficient/step size for buy and sell trades in a grid set
If we can have separate lot co-efficient/step size then by using TDI/Identify parameters in Day/4H time frame, we can adjust them when it is against the trend.
Say for example, if TDI Day indicates buy, then we will increase the above parameters in such a way that we will take less trades in sell either by increasing the step size, reducing the lot co-efficient etc.
If TDI(Day) is buy, then use step size of 2x or 3x for sell.
In this way we can reduce the DD with a Grid set.
It should be parameter for each filter.
Something like "Lot adjustment coefficient".
It will increase all lot sizes if signal is co-directional and decrease them if signal is opposite.
Don't know how it will work, but we can try.
