Both are irrelevant, because we cant control the outcome of a trade, nor we can be 100% of the time available to take the trade.
Worst case: taking a winning trade by not following your rules
As TheRealDeal said, they don’t mean nothing by themselves. However, I may add, they may have a meaning if you match the entry (or not entry) with your trading plan. If you enter and lose, or if you don’t enter and you see it go according to your mental bias, both are good or bad depending on whether your plan tells you to enter or not. Is a good trade is you took it out of your plan, even if you lose, and is a good trade if you didn’t take it even if it went as you “predicted”, so long as your trading rules tell you to keep away from the markets.
