Semaphore arrow signal indicator based on the QQE oscillator. Signals are generated when there is a crossover of the main and the signal oscillator line.
The indicator uses SmoothAlgorithms.mqh library classes (copy it to <terminal_data_folder>\MQL5\Include). The use of the classes was thoroughly described in the article “Averaging Price Series for Intermediate Calculations Without Using Additional Buffers”.
