This trade looks so silly that suggests chasing GBPUSD after a 250pips rally. While in terms of inside bar after new high trade, the only indicator to define whether it's too extended to long is 8EMA, if the 8EMA is able to catch up the inside bar low, it's still not too crazy to trade!
Again, I only want to long in such a uptrend, so I won't take the short if it breaks to the downside; if the breaks to the downside first, than this trade doesn't exist anymore.
