This is a prime example of not trusting your gut when you see a high probability setup, the fact that you risked too much money on a similar setup and lost on it is influencing you to be afraid to trade whenever you see a similar setup, you naturally feel that big losing trade again, even though the odds are in your favor you give into how you “feel” from a previous trade. If your trading edge is a pin bar setup with the trend, you must take every high-quality pin bar setup with the trend, if you start becoming fearful because you lost on one or two of them, eventually you are going to miss very lucrative setups, this is going to have a very negative impact on your trading psychology and cause a landslide of emotional trading mistakes.
