The following counters need to survive multiple executions of the similator and keep themselves reliable.
This is challenging when the simulation is executed using Daily Files, since each execution means a new
day and these counters are meant to be kept along the whole market.
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.
To overcome these challenges we record the values of the counters and variables on the interExecutionMemory only when
the day is complete and if we have a current Day. That menas that for Market Files we will never use
interExecutionMemory.
