Mr Olchawa strategy for the contest was trading only EUR/USD looking for opportunities of strong breakouts from side trends. With technical analysis he extracted periods with high probability of strong breakout. Obviously for the competition he played with high leverage using predefined Stop and Profit levels, trying to minimize time when he had open positions. All trades were performed manually.
