Martingale Entries Don't Appear to be Truley Random on Sample cBot

effectively...the robot is built for a first random order ... then it stays in the same direction ... and it leads to disaster if you are in the wrong direction for a long time.
test this one ... it is completely random.
Warning ... you will never do the same backtesting

//    profit of any kind. Use it at your own risk
//
//    The "Sample Martingale cBot" creates a random Sell or Buy order. If the Stop loss is hit, a new 
//    order of the same type (Buy / Sell) is created with double the Initial Volume amount. The cBot will 
//    continue to double the volume amount for  all orders created until one of them hits the take Profit. 
//    After a Take Profit is hit, a new random Buy or Sell order is created with the Initial Volume amount.

I suppose every trader needs to go through the "Martingale" stage in there trading journey as a rites of passage..........
