PFC Megaphone Short would the History Repeat?

The Price movement is forming Broadening Formations(Megaphone) Right-Angled and Ascending. Last time it has retested the level within 7 Bar and moved down till the other end. Interestingly it is forming the similar move again Let's see if history repeats. Anyway the pattern is picture perfect, Stop Loss is affordable and Risk to Reward is attractive what else should we look while framing the trade. My only Concern is Budget Day volatility.
