I have found a minor issue with Share Trade Tracker and it may impact performance results on mean reversion systems.
Currently STT is picking up the dividend if a position is entered on the ex-div day. The dividend is only applicable if the stock was owned prior to the ex-div day. A MR system will tend to enter on ex-div days as the stock dips and in STT that position may be credited with the dividend which is incorrect.
The developer will make a fix on the next update.
