my main strategy is a kind of swing trade, but yes indeed I do take shorter term day trades within these multi-day swings. The danger however is that then these multiple trades are all in the same direction, so I must take care the total leverage per position does not exceed my own guidelines. In general I agree the 2 styles complement each other, and if the systems are well chosen shoudl smoothen the curve. I have not found good tools yet to properly evaluate the effects of multiple strategies in one account. By effects I mean proper money management so that risk is managed within my limits.
