The expert Advisor trades according to the Market Sentiment and the direction set by the trader-against the market or following the market. Information about Market Sentiment is taken from the MyFxBook page, which shows the number of trades in the market to buy and sell, as well as the volume and average prices of buys and sells for all instruments. Since the Market Sentiment history is not provided, the expert Advisor saves it to disk for possible subsequent use during testing and optimization. On the discussion page of this expert there is an archive with the Market Sentiment history of some tools.
