This is to speed GSB up. With the default settings, if there is <1 trade per year or the netprofit < $1 after 20% of the bars in the data file are processed, GSB will abort the iteration and go on to the next one.
Terminate Strategy's backtest (During Optimization or Walk-Forward) after % bars (of the full period) if performance does not pass the specified criteria. It is mainly used to increase optimization speed.
Note: Rest are very same as performance Filer's. So no further discussion needed.
Use currency for futures, Percent for stock.
