Great question jmlocatelli!
As is, the code assigns an equal share of funds to each asset bought.
You have the option to use assetWeight[assetSorted[i]]/totalSlope instead of just dividing by enterNum to calculate the Lot amount.
That would assign funds to each asset bought proportional to its momentum value in comparison with other bought assets.

// Note: The following is optimized for 2x leveraging!
Lots=(Capital+WinTotal-LossTotal)*Leverage/(4*enterNum*price()*LotAmount);

How would you optimize it for 5 times leverage?

I hope it's not too late to revive this topic.

First of all, congrats to OP for coding your own dual momentum strategy!

I'm also working my own flavor dual momentum recently. The biggest problem I have is understanding how to properly do a reality check on a trend following, reinvesting strategy such as dual momentum.

Is it necessary to detrend PRICES for the benchmark result of reality check? As this will remove the trend, it really messes up the results. Any advise and maybe explanation on when and why this would be necessary?

// Reality Check
NumTotalCycles = 1000;
if (TotalCycle > 1) Detrend = PRICES+SHUFFLE;
else Detrend = PRICES;
set(LEAN,PRELOAD);

Or is it enough to just do it this way?

// Reality Check
NumTotalCycles = 1000;
if (TotalCycle > 1) Detrend = SHUFFLE;
set(LEAN,PRELOAD);
