Add a third criteria for a trend reversal EA

I have a stratergy for predicting trend reversal and then entering a trade in the opposite directions. The criteria I use are:

(Say, before I predict a trend change from downwards to upwards, in other words before for opening a long trade)

Condition 1: The Bollinger band should cut the bottom band.

Condition 2: RSI must show over-sold signal.

Now the EA handles this very well, and I do not want to change any of these 2 criteria. However, I would like to add a third criteria before I can confirm trned reversal and open a trade in the opposite direction (in this example, before I open a long trade)

Condition 3: This condition is for the top bollingerband to go flat. (Please see picture below).

So, after condtion 1 and condition 2 are met, the EA checks and waits for upto 8 candles until condition 3 is met… As soon as condition 3 is also met, it opens the reversal trade.

Please see attahcment for detailed picture.
