There are few factors that leads to unfavourable trading, these factors includes Greed, and chasing a trend, Traders are expected to encounter Challenges during trading and relating these challenges with people's experiences can be the key in solving the challenge,
Sticking to the trading plan is also good to avoid unfavourable trade as changing plans in the middle of a trade Can really lead to a loss in trade.
Money matters are not without their risk, except it is not money we are talking about, but if it is to gain money and even gain a whole lot of it, then one must be ready for the risk and overcome the challenges they might face therein. That is why trading has to be handled professionally, and with the needed experience and creativity, this may not be impossible. I pity those who are trading and can't handle their psychology, it is such that will get them in trouble, that is where the greed and fear come in, and those traders who have these two are already emotional, and there is nowhere emotion will dive you if not into ruin. Once a trader loses, I believe the better one should be happy still and let go of it real quick to help himself indirectly.
This is what is helping me when I am more experienced about trading, if not, emotion can set in and before you know it, that might be the end of the account. Doing what others hardly do in trading is a very good way forward and instead of looking for the best trading strategies that will give you 100% winning, why not just try to find the one that can give you at worst 75% winning strategy then you cover up for the weakness with a proper money/risk management along with very good trading psychology. With these in place, you know when to trade and when to wait, and even if you lose, it won't affect you or your trading account so much because you will be able to manage yourself and your trading account.
This is the rule that preserves trading success longer.
