What we must realize from the outset when trading is that we must recognize that profit and loss will always go hand in hand; we cannot eliminate either one. But can we minimize losses? Of course, we can minimize losses by improving our knowledge and skills. But can we avoid losses when we become highly skilled? The answer is no.
That's why a trader must be disciplined in carrying out their activities so that they can control both losses and profits and be able to make adjustments. Often, many traders achieve consecutive profits, but a single loss wipes out all their capital and previous profits. This is based on incorrect trading techniques, and generally, they don't use stop-loss in their trading activities. In fact, I myself have experienced eight consecutive profitable trades, only to experience a single loss, which wiped out everything. Skilled or not, no one can avoid losses because trading carries significant risks, even if the trader is professional and highly knowledgeable.
There are also those who can make a profit, but their previous losses are also substantial, and those profits aren't enough to cover the losses they've already incurred. This can cause problems, because when they lose, they might start thinking about how to recoup their previous losses.
And if that happens, their trading will be heavily influenced by emotions because their ambitions are too high, while we know the market is highly volatile. Instead of trading, they might become like gambling.
