Added a new selectable rule for starting a deal -> SNV
SNV in this case stands for "Stochastic and Volatility": If the stochastic on the selected timeframe is above a threshold, and the current volatility has a high percentile compared to earlier readings, begin a deal.
Added a selectable mintick, allowing the the rounding of order price values to a custom number, fex if the exchange has orders with a price difference of 0.5.
Fixed a bug with Deal Start Condition 2 where it might enter a deal even if no condition was selected.
The information box will now display an error if the timeframe selected on any Deal Start Condition 2 is below current chart timeframe.
