EURGBP long with an alternative bat for bigger correction

FX:EURGBP   Euro Fx/British Pound
I use the harmonic alternative bat in conjunction with channel as my entry technique to go long. With this entry I'm taking an agressive CD leg of the AB=CD pattern.

Also, RSI is showing sold out conditions at the 4H. The Daily chart is showing a tap to the midline of the Bollingerband and a RSI stalling at the 50.

My stops will go below 0.7213. Still the risk to reward ratio is more than 1:4.
Is there a "trigger" or a condition you need to see that turns this trade "on" from sitting on the sidelines? I could use a little more understanding. Thanks.
If the current candlestick (4H) closes as a doji after 3 consecutive bearish candlesticks, I would consider this trade as triggered for an aggressive playing style. Ah I'm too late with the reply..
But my original trigger was hitting the 0.72508. Because I've entered with an alternative bat setup with a alternative D point at 0.72508.
Well, a bullish engulfing would another trigger as well to enter this trade
Well Tim, there is another "trigger" to go long: RSI bullish divergence with an exhaustion gap. This kind of signal gives me more confidence to go long.
