Say you want to trade two systems that anti-correlate with each other, such as a trend system, "system A", and a counter-trend system, "system B". You have backtested and found that when one is losing money, usually the other is making money. What if when system A is in a drawdown, you reallocate a percentage of system B's resources to system A? You would be counting on a reversion to the mean. Alternatively, you could increase resources to the currently profitable system at the expense of the system currently in a drawdown. This would be a trend strategy in itself. Does anyone do this? Would this be a money management technique or is this another strategy altogether?
