The strategy is simply depending on indicators CCI and Stoch, and
Exponential Moving Average (EMA). sell is triggered when the last bid
candle closes price less than EMA value, SlowD value in Stoch is
bigger than or equal to 75, last bid candle open price less than last
bid candle close price, and CCI value bigger than or equal to 100
value. vise versa for buy stage.
