I installed and got this error - Default    Strategy 'SniperSlingshot': Error on calling 'OnStateChange' method: 'AddDataSeries' method: There exists no implementation for this 'BarsPeriod' object.

 

Not sure if its to do with my NT version (8.1.5.2 64bit) or there is an error in the code.

I got the same error, i think it only works with the sniperbars, do anyone have those bars?

Got home, installed without any problems, however, I dont have the buttons on show, is there anyway to make them 'show' ? Any help would be very awesome. Thanks
