I think emotions and 'feel' are incredibly useful in trading, used in the right way.
It makes sense that you feel confident about the trades you're in. It's not a cause and effect relationship though.
It's not that when you feel confident, 'shit works' and when you fell less confident it doesn't work. It's more along the lines of... you feel confident due to a bunch of different factors and those factors result in a trade that is successful and may have an edge.
Don't fall into the trap of thinking confidence is the reason for a successful trade, it's not, it's a symptom, but also a trigger.
When you correlate confidence with the reason for a successful trade you put yourself in a situation of 'overconfidence' where you think that the confidence and success of your last trade will somehow correlate into the success of your next one. This is dangerous with trading as you can do all sorts of retarded shit and still make money, developing detrimental habits.
Take this situation for example. You look at several reasons for getting into a trade and it works out flawlessly. You see the context of the market, a few trading gambits and familiar patterns and you execute. You feel confident because you think you've observed something with an edge. It has an edge 'clearly' and it works out. You then feel good and get into the next trade, you look at the same factors with less focus, but you feel good, your 'confidence' becomes one of the factors you use to determine how to execute. Another success. Eventually you start to correlate confidence with success and look less and less at the factors that brought about that confidence and initial success. Soon you start using confidence as a sole reason for entering a trade.
I may be completely off target here but I think the reason why you described your experience as 'weird' is because you're slipping into this process. You've gotten into trades purely on confidence and they've worked out. You may be shifting the % of your focus from an actual edge that's well thought out to replacing that % with confidence. It might work for a while, just like flipping a coin, but it's not a consistent edge.
Confidence is good as a 'trigger mechanism' to adjust your focus, provide you with information, the speed to execute etc etc - but it shouldn't be a big 'factor' in deciding what to trade. It certainly shouldn't overpower what you look for to get an edge. You're confident because you've seen the factors that look like an edge and you execute, you don't execute just because you're confident, a huge difference, but an easy trap to fall into given the way our minds are evolutionary wired.
Re-assess your decision making honestly and try to determine how much is based on confidence and how much is based on a genuine thought out edge.
What all the old boys who trade on feel fail to mention is that their confidence and 'feel', is mainly based on experience. They aren't confident because they had a couple of winners in a row and they feel invincible. They feel confident because they're looking at a pattern they've traded 100 times before. Their emotions are piqued initially because they see a few signs it's developing, they call it 'feel' but it's mainly memory and pattern recognition - they then use that confidence as a trigger and execute.
Confidence is the trigger, but because they're so experienced and 'unconsciously competent' in executing their setups they can't explain what happens after the trigger and erroneously say it's all due to 'feel'. It isn't, the 'feel' is just the trigger for a set of highly refined and learned behaviors and actions developed over years.
It's a very, very different form of confidence and 'feel' to someone that just feels good about their trades due to a good string of outcomes.
Overall, what I'm trying to say is that there are two different types of confidence, before and after, or execution and residual confidence. When dealing with something like trading that's based on probabilities you have to really take the 'residual' confidence with a pinch of salt, it will catch up to you if you lack self awareness.
If you're a surgeon that's performed 100 routine successful operations, then that residual confidence is great it keeps you driven, you have more control of the outcomes and that confidence helps you to perform your next operation. Not in trading, residual confidence will destroy you, you don't have control over the outcomes in the same way. When you start replacing your edge with a confident 'feeling' rather than using confidence as a tool to enhance your edge you're sliding down a slippery slope.
