To overcome this problem, we use the interExecutionMemory to record the values of the current execution when finish. But there are a few details: 1. When the process is at the head of the market, it executes multple times at the same day. 2. The same code serves execution from Market Files. 3. In Daily Files we are receiving candles from the current day and previous day, so we need to take care of not adding to the counters duplicate info when processing the day before candles.
