After a fall like that, just one green candle on its own wasn't enough evidence - after seeing two greens close side by side you saw a possible reversal signal?
But a V shaped formation might not have given you time to enter on the break of a previous high - so you simply place a market order at the top of the zone and grabbed any pips offered?
