Error: Confusing trading with investing. Many traders justify taking trades because they think they have to keep their money working. While this may be true of money with which you invest, it is not at all true concerning money with which you speculate. Unless you own the underlying commodity, for instance, selling short is speculation, and speculation is not investment. Although it is possible, you generally do not invest in futures. A trader does not have to be concerned with making his money work for him. A trader’s concern is making a wise and timely speculation, keeping his losses small by being quick to get out, and maximizing profits by not staying in too long, i.e., to a point where he is giving back more than a small percent of what he has already gained.
Error: Copying other people’s trading strategies. A floor trader I know tells about the time he tried to copy the actions of one of the bigger, more experienced floor traders. While the floor trader won, my friend lost. Trading copycats rarely come out ahead. You may have a different set of goals than the person you are copying. You may not be able to mentally or emotionally tolerate the losses his strategy will encounter. You may not have the depth of trading capital the person you are copying has. This is why following a futures trading (not investing) advisory while at the same time not using your own good judgment seldom works in the long run. Some of the best traders have had advisories, but their subscribers usually fail. Trading futures is so personalized that it is almost impossible for two people to trade the same way.
Error: Ignoring the downside of a trade. Most traders, when entering a trade, look only at the money they think they will make by taking the trade. They rarely consider that the trade may go against them and that they could lose. The reality is that whenever someone buys a futures contract, someone else is selling that same futures contract. The buyer is convinced that the market will go up. The seller is convinced that the market has finished going up. If you look at your trades that way, you will become a more conservative and realistic trader.
Error: Expecting each trade to be the one that will make you rich. When we tell people that trading is speculative, they argue that they must trade because the next trade they take may be the one that will make them a ton of money. What people forget is that to be a winner, you can’t wait for the big trade that comes along every now and then to make you rich. Even when it does come along, there is no guarantee that you will be in that particular trade. You will earn more and be able to keep more if you trade with objectives and are satisfied with regular small to medium size wins. A trader makes his money by getting his share of the day-to-day price action of the markets. That doesn’t mean you have to trade every day. It means that when you do trade, be quick to get out if the trade doesn’t go your way within a period of time that you set beforehand. If the trade does go your way, protect it with a stop and hang on for the ride.
Error: Taking a trade because it seems like the right thing to do now. Some of the saddest calls we get come from traders who do not know how to manage a trade. By the time they call, they are deep in trouble. They have entered a trade because, in their opinion or someone else’s opinion, it was the right thing to do. They thought that following the dictates of opinion was shrewd. They haven’t planned the trade, and worse, they haven’t planned their actions in the event the trade went against them. Just because a market is hot and making a major move is no reason for you to enter a trade. Sometimes, when you don’t fully understand what is happening, the wisest choice is to do nothing at all. There will always be another trading opportunity. You do NOT have to trade.
Error: Taking too much risk. With all the warnings about risk contained in the forms with which you open your account, and with all the required warnings in books, magazines, and many other forms of literature you receive as a trader, why is it so hard to believe that trading carries with it a tremendous amount of risk? It’s as though you know on an intellectual basis that trading futures is risky, but you don’t really take it to heart and live it until you find yourself caught up in the sheer terror of a major losing trade. Greed drives traders to accept too much risk. They get into too many trades. They put their stop too far away. They trade with too little capital. We’re not advising you to avoid trading futures. What we’re saying is that you should embark on a sound, disciplined trading plan based on knowledge of the futures markets in which you trade, coupled with good common sense.
“I know it may sound strange to many readers, but there is an inverse relationship between analysis and trading results. More analysis or being able to make distinctions in the market’s behavior will not produce better trading results. There are many traders who find themselves caught in this exasperating loop, thinking that more or better analysis is going to give them the confidence they need to do what needs to be done to achieve success. It’s what I call a trading paradox that most traders find difficult, if not impossible to reconcile, until they realize you can’t use analysis to overcome fear of being wrong or losing money. It just doesn’t work!”
