The trading system based on the three Stochastics signals from three different timeframes. The two Stochastics are used to define a trend direction by the Stochastic location relative to a signal line. The third one is used to detect a crossing of the Stochastic and the signal line. The signal is formed when a bar is closing if there is a crossing of a lower-timeframe Stochastic with medium- and higher-timeframe ones by trend.
