Yes, I can confirm that max is 20, and I tried to change it in System\instruments.xml file, however, system crushes with following error:

I suggest you use 4 digits data, it is very simple to change just use Excel 2007 it can hold 1million records. (2003 only 65k).
However, I personally would not trade with broker which has more then 2pips of slippage, any way. I have traded a lot and did not see this is the case, as all disant brokers keep quality now, I remember FXCM had this issue, but it was more then a year ago it was fixed then they moved to Boston Tech.
Alpari/Oanda/dukascopy/ don't never had issues.
