I'm glad you asked.
Yesterday on the reversal short, because of the way the order is handled internally, the PDT rule came into play. The sell order was filled, the short sale was not. The IB acct that I was using for CSCO only has 15K in it.... hence the PDT rule problem.
Looking at the historical chart this is not routinely a problem. But it did cost profits today, profits that would have moved the account into positive territory, profits that were a part of the whole p/l picture and profits that are a part of the historical picture when looking at the chart.
So actually I am flat. But this is just the type of unforeseen circumstance that gets in the way of realizing the profits it looks like you should from the charts. Specifically, many if not most of the times the price crosses on a closing basis and does not cross back, or not so right away, thus avoiding the PDT rule.
The present short position SHOULD be up 22 cents presently, and 6 cents overall.... but more importantly....
.... the illustration of what I am talking about with whipsaws. You know price is going to deviate from the mean, that is why you selected this candidate. Usually price does not crsiss-cross across the mean. That is visually evident from the charts. SO what if it goes criss then cross then criss again before it goes. The profit right now is 6 cents, the profit potential has been 21 cents so far.
