Have you accomplished any activities before the strategy being changed?

This is only possible if ticks comes from a different chart. FSB doesn't set symbol or period. Do you change the MT4 chart period during trading?

Such beahiour is possible if there is another connection form other copy of FSB Pro or from FST.

Today, one of my strategies, add lots even when I didn't turn on this function and also instead of buying 1 lot, it open trade with 8 lots! Wow, good thing, it's in demo account

Also from time to time, I realized that the strategies I saved changed in it's setting such as time frame changes to a different time period and hence, changes the profitability of the strategies.  So when my strategies started not to "behave" as the pass few weeks, I wonder why and when I stop my trades and switched to edit it in builder mode, I noticed it was not in the original settings I first started...strange.
