   Lots - Lots is fixed, without money management, it must be manualy adjusted to 10K USD
   SL, TP it means 2000 for 5 digits, 200 for 4 digits brokers
   UseTrailingSL - Only when SL pip size value is set
   ProfitUSD - Close all positions if AccountProfit() reach ProfitUSD value percent, if you adjust Lots size you must adjust also Profit and LossUSD size with the same ratio
   LossUSD  - Close all positions if AccountProfit() reach LossUSD value (remember the realtion between LossUSD, ProfitUSD and Lots size!!!)
   LossUSDTrade = Close immediately trades with this loss (USD)
   CounterTrend = Its means that our signal can give us opposite information. Just use it on some markets
   OpenBarEnter = process only at each bar open
   HighLowBars = number of bars where we search for iHighest and iLowest
   SameOrderAfterPips = Open another order after X pips (10pips = value 100 at 5 digits borker)
   OppositeLotsMultiplier = Multiply sum of opened lots for opening in the opposite direction (if signal indicating trend change)
   DirectMultiplier = aggressive Lots multipling of new opposite orders
   ReverseClosePositions = close all opposite orders if there is opposite signal
   LotMaxLimit = Max lot value for each new order
   TimeStart = start hour 0 - 12
   TimeEnd = end hour 12 - 24
   SignalMode = 1: MA crossing slow MA (in uptrend), 2: MA crossing slow MA, 3: MA crossing slow MA with price, 4: MA crossing slow MA with price and Williams Perc Range was  in the zone, 5: MA crossing slow MA with price and Williams Perc Range is crossing out from overbought or oversold zone
   EAPeriod =  Period for indicators MA and iHighest and iLowest, 0 = M1, 1 = M5, etc... see the init() section
   FastMAMode, SlowMAMode: 0 = sma, 1 = ema, 2 = smma, 3 = lwma
   yMAShift = MA shift for previous MA values
