I could need some feedback from somebody else on my work on primers so far…
General idea of primers:
P1 slows down P/L fall. P2 slows it down some more. P3 starts P/L increase. P3 has to trigger before free margin hits 0. Guideline: “Turn equity within 150 pips”.
Problem:
Retracements close primers and imbalance returns.
Specifics:
1: There is a certain drawdown price per pip as P1 opens. From that we can calculate how far rate can drop until free margin/equity is 0. P1 will extend that by a calculable distance, so we could get a number from this for distance to “point of no return”.
2: If P1 is hit by SL and P2 is twice the size, P2 will maintain the same rate of decline that P1 alone would have achieved, so “nothing has changed”, but remaining distance to collapse point, hence size need to increase to make up for smaller distance.
3: P3 will need to be bigger than P2 since there is less distance to collapse point, but not twice the size, as we now have secured profits from P1 for at least 1 primer step.
4: P4 will need to be bigger than P3 again, but minus P12 steps + P21 step.
Or will it? We can get new primers with 0 profits from the previous ones with the right level of repeated retracements. We can reopen closed primers after large retracements, but we would then loose the trailing stoploss security and can end up with multiple open primers against the trend.
Conclusion:
Primers need to grow, and should be calculated from size * remaining distance - other open primers + “security buffer”.
Channel extensions:
I use a trailing stoploss for primers and update channelTop/Bottom (which decides where regs are placed) based on the highest short primers SL and the lowest long primers SL. If we change regs to neutral positioning (exact same open price), then retracements from short primers will mean that Ask will trigger a newly added pending long before the first pending short, and opposite with retracements from long primers Bid will hit new pending short first (Ask is always higher than Bid). This will at least improve P/L a little. Not sure about the consequences for regs in general inside the grid.
