//  Description
//  =============================================================================
//  This strategy will go long if fast MA crosses over slow MA.
//  The strategy will exit from long position when the price increases by a fixed percentage.
//  If the trailing take profit is checked then the strategy instead of setting a limit order in a predefined price (based on the percentage)
//  it will follow the price with small steps (percentagewise)
//  If the price drops by this percentage then the exit order will be executed
//
//  The strategy has the following parameters:
//
//  Fast SMA Length - How many candles back to calculte the fast SMA.
//  Slow SMA Length - How many candles back to calculte the slow SMA.
//  Take Profit % - The percentage of the price increase to set the take profit price target.
//  Enable Trailing - Enable or disable the trailing for take profit.
//  Training Take Profit Deviation % - The step to follow the price when the take profit limit is reached.
//  Trailing Stop Loss % - The stop loss percentage drop that will close your position. After the take profit price is reached the trailing stop loss price target will follow the price upwards (for long positions).
