Is having the correct direction more important, or is position management?

My solution is 12345+ABCDE

Many people trade, spending most of their energy on "guessing the direction"—studying various indicators, drawing lines, finding support and resistance, as if just knowing in advance whether the market will go up or down makes making money a matter of course. But those who truly survive in the market all understand: accurate direction is just the icing on the cake; position management is the foundation of survival.

It's not that direction isn't important. Of course, having the right direction is good, but the market is never 100% predictable. You might guess correctly nine times in a row, but on the tenth time, if you go all-in and the market moves against you, you could give back all your previous gains, or even lose your principal. Direction judgment addresses probability, while position management ensures you can stay alive in the trading market.

I often say during my live streams: when the market moves out in patterns 1, 2, 3, 4, 5, we have responses A, B, C, D, E. That is, you need to preset multiple possible scenarios—up, down, sideways, trap longs or shorts, deep retracements... For each possible scenario, you have a corresponding action, rather than betting on it definitely going a certain way. And for all these "response actions" to be executable, the only prerequisite is: your position size must not let you lose control. If your position is too heavy, you'll start fantasizing, holding on through losses, or hesitating to cut losses when you should. With a reasonable position size, you can calmly implement Plan B, Plan C—no matter how the market moves, you won't panic.

So, returning to this question: is trading more about the importance of direction or position size? My answer is—direction gives you the chance to make money, but position size gives you the chance to keep playing. In the long run, those who are truly consistently profitable are not because they have divine market judgment, but because they know how much to risk each time, and even if they miss a few trades in a row, they won't get hurt badly. Use position management as insurance against uncertainty, then focus your remaining energy on refining your plans, rather than obsessing over "I must be right."

Having expectations and prepared responses for multiple market scenarios is a sign of a mature trader. Master good position management and prioritize it.
