Operation of the CodEx 4 Expert Advisor is based on patterns composed of consecutive candles. Positions are closed when opposite signals appear.

Sequences of candles are encoded into an integer according to the following rule. The code number must be converted to binary form and the highest bit must be discarded. The resulting sequence of bits encodes a continuous sequence of candles, where 1 is a bullish candle, 0 is a bearish candle. The higher bits encode the earlier candles. For example: 19[10]=10011[2], the obtained sequence of candles is [bear][bear][bull][bull].

In the input parameters, the patterns for buy signals are encoded. The EA obtains the patterns for sell signals by inverting the initial patterns.

Input parameters
