I want an automatic trading robot that uses 3 EMAs; 5EMA, 10 EMA & 20 MA. Signals as follows, when 5 EMA crosses 10 EMA from below such that 5EMA > 10 EMA, a buy order should be executed upon close of the candle, also  same for when 5EMA crosses 20EMA from below, a buy should be executed and vice versa for a sell position for both EMAs...trades should be closed when the 5EMA crosses in the opposite direction for both situations and immediately open a new reverse trade.
