It's hard for jgp to understand why many members of the community use the increase in "volume" [effectively #ticks/unit-time] indicator to trigger opening a position, while I seem to be the only member who thinks it might be a useful trigger for closing an open position.  Master Popov says it would be easy to add such a trigger to the  FST Expert.  Alternately, it might be possible to add it to the Stop Limit indicator which apparently now keeps track of the price value of each tick and exits the open trade when the SL or TP setting is reached.  If most members of the community don't want the "excess volatility" trigger on the FST EA, aren't there more than a few members who would like a revised Stop Limit indicator?  if it can be done?

My bad..  upon further investigation, I conclude that "trails once a bar" simply means that the exit criteria appropriate to the previous bar is used when considering whether to trigger an exit [ tick by tick?] of an open position during the current bar, not waiting till the end of the bar.  So I conclude that in principle it should be possible to add a "percentage increase in volatility" limit to the Stop Limit indicator  used for  triggering the Closing Point of the position.
