Hide EA_v3

The expert advisor has 3 modes for opening/closing positions: High Volatility Mode, Low Volatility Mode and Low Volatitlity Extra Mode.

-I need a Close all positions function that will trigger every time that the Volatility function has shifted from Volatility<=Vtrigger to Volatility>Vtrigger or viceversa. This function must trigger just once for each time there has been a shift.

-The 3rd mode is the Low Volatility Extra and it needs to be created by you. This mode's job is to add more lots to the current trade opened in the Low Volatility Mode. There are 2 conditions: Volatility<=Vtrigger and the duration of the current trade is equal to 30 natural days (this value should be modificable, 20 days, 100 days...). This means that while Volatility<=Vtrigger, ONCE per month a new long/short order must be created (long if ama>Spivot, short if ama<Spivot) increasing the original lot size created in the 2nd mode. The lotsize for the 3rd mode is already defined in the EA, it is called LotsLowVextra.
