The strategy is based on the principles of martingale. Strategy trade on EUR/USD currency pair, at any time of the day. The strategy does not use any patterns and indicators. Entry point is pretty basic - if the last candles direction is bullish - strategy going to open Short trade, and vice versa for Long trade. Time frame 10 minutes. Stop-loss is 15 pips, Take-Profit is 30 pips. Initial position size - 2.0 million. If the position closed by stop-loss - the size of the following trade will be increased by 1.8 times (2.0 - 3.6 - 6.48 million...etc) to compensate the loss from the previous loss trade. I think that this combination of stop-loss/take-profit and increasing factor the size of the next trade after losing trade - is an optimal combination of profitability and safety.
