Dear all, A number of indicators making use of the two above mentioned functions have been circulated with the aim of showing the ratio at higher timeframes. I suspect that using these indicators for testing systems in higher timeframes in MS EOD produces an element of hindsight that generates better results than obtainable in real life. I suspsect that this is due to the fact that data for the current week is dynamic while data in history is fixed. This can explain differences observed in System Tester between results obtained with indicators using the above functions + daily data AND normal indicators with weekly data. The conclusion would be not to use indicators with the above PP functions embedded in them and higher timeframes in System Tester. Could somebody with more experience in these functions confirm this point? Thanks. Maurizio
