RandomGambler strategy is cross over of choosing (almost) random Order
(between BUY and SELL) and martingale system. This naive system is
constrained by taking profit at 10 pips and stop-loss at 10 pips. Each
order is doubled if the last trade had a loss.
# 1.2 version updates the strategy to pick Order Command randomly
between 4 options - 2 hardcoded and 2 from Indicators (So it's only
close to random now).
