Stevea2980,
My thinking goes like this.......
If you are X_DEV'ing a play, be it the QQQ's or any other stock and it goes to all cash but price continues higher in the following 2 - 3 days, then consider re-entering with a partial amount.
Where you re-enter and how much is of course up to you but here are some suggestions.
1) Immediately re-enter at the market at open the next trading day with a 50% position. Then disregard the X_DEV sell signals until a full turn has occurred. By "full turn", I mean waiting until price has dropped to a buy signal (lower band) and then gone all the way up to another sell signal (upper band).
2) Immediately re-enter at the market at open the next trading day with a 25% position, then wait for a dip to the 12 day ema (exponential moving average) and buy another 25%. Then disregard the X_DEV sell signals until a full turn has occurred.
3) Wait for a dip to the 12 day ema and enter with a 50% position. Then disregard the X_DEV sell signals until a full turn has occurred.
4) Don't do anything, and just wait for X_DEV to signal the next best buy when price has reached the lower band.
Using suggestion 1, 2 or 3 above gets you back in the market, so if it continues to rise at least some of your coin is working for you. If the market fades, you still have some cash left to buy more shares at a more timely opportunity.
Suggestion number 4 is the safest suggestion, but requires more patience. It is easy to get frustrated seeing your stock continue to rise while you have sold and are parked in cash, but believe it or not, stocks DO fall and will come back to the lower X_DEV line. Hard to believe I am even stating this simple fact after 2 1/2 years of the worst bear market anyone here has ever seen.
