While I didn’t look specifically at the longer-term trend in that post, it is often helpful to put studies into their longer-term context. The last couple of days QQQQ has closed above its 200-day moving. Below I broke down the results of the original test into those times it triggered below and above its 200-day moving average.
Filtering by the long-term trend can have a dramatic effect on certain studies. QQQQ is the first major index to cross its 200-day moving average. Should the rally continue and the other major indices follow it will be important for traders to keep the long-term trend in mind when considering trades.
