Anyone know more specifically how "control points" mode in the strategy tester is calculated? I see that its "based on the nearest less timeframe", but I'm interested in understanding that a little deeper.
From the article: STRATEGY TESTER: MODES OF MODELING DURING TESTING
Control Points (the nearest less timeframe)
Method of modeling control points is intended for crude estimate of Expert Advisors trading within a bar. To use this method, historical data of the nearest less timeframe must be available. In the some cases, the data available from a smaller timeframe do not completely cover the time span of the timeframe under test. If there are no data of a smaller timeframe, the bar evolution is generated on basis of predefined wave templates, as it was the case in the preceding third version of MetaTrader 3 Client Terminal.
As soon as historical data of the less timeframe appear, these are these data that are interpolated. However, the really existing OHLC prices of the less timeframe appear as control points. In the most cases, the results of tests of Expert Advisors by method of control points can be considered asestimated results only, not as final ones. Such results are of intermediate, estimated nature. The chart below shows how the on-hour bar of 2007.09.05 10:00 developed by method of control points.
