A typical scan of QQQ ETF constituent stocks for price action anomalies as of the close of Monday, December 18, 2017, yielded three signals that were all profitable next day.
The scan generated long signals for two stocks, QVCA and ROST, and a short signal for one stock, XRAY.
All signals were profitable from the open to the close of the following day. One of the signals was a long in QVCA that gained 2.4% from open to close after rising as much as 4.4% from open to high of the day.
The DLPAL DQ scan results as of the close of Monday, December 18, 2017, are shown below:
Below is the performance of the signals in the following day, Tuesday, December 19, 2017.
| Signal | Close to close | Open to Close | Open to High |
| Long QVCA | 3.2% | 2.4% | 4.1% |
| Long ROST | 1.3% | 1% | 1.3% |
| Short XRAY | -0.1% | -0.06% | 0.66% |
Note that the above scan results can be replicated with a demo version of the program (fully-functional for two weeks.) The scan workspace used is shown below:
For the daily scans we use adjusted data starting on 01/03/2000. We update the data daily and then re-run the scans. We also do that for various other stock groups.
Note that 100% winners in results is rare result but demonstrates the potential of the software. There are high risks in trying to identify price action anomalies due to periods of time when quantitative analysis cannot differentiate successfully between the signal and the noise in data.
