The third version of the strategy. Timeframe period changed to 15 minutes. The strategy is based on Japanese candlestick patterns. In this strategy, I use a combination of 2 Japanese candlesticks. We look at 2 bullish candles: if the body of the second candle is larger than the first, we buy, if it is less, we sell. 2 candles are bearish (positions are opened vice versa): if the body of the second candle is larger than the first, we sell, if it is less, we buy.
