Here we assume that the last day written might contain incomplete information. This actually happens every time the head of the market is reached.
For that reason we go back one day, the partial information is discarded and added again with whatever new info is available.
The stairs objects can span more than one day. In order not to cut these objects into two when this happens, this process will alsways read
2 files. The previous one already processed, and the current one. That means that it will allways re-process the previous one, until the
last moment in which the previous one turns into the current one. By doing so, we avoid breaking the objects when day changes.
So you will se we go 2 days back. One if because of the above explanation. The second is because we enter the loop by advancing one day.
