In reality, there are two reasons that constrain: one is withdrawal, that is, the handling fee, and the second is the maximum order limit. This is also the case in the contract market, where there are influences from handling fees, slippage, profit and loss ratios, etc. Although there is leverage support, it can also be affected by the amount of capital.
For example, if you initially open an order of 250u and lose, then open 500u and lose again, then open 1000u, and continue this way, can you make money with a win rate of over 50%? The answer is quite obvious, you cannot. This is because each order has a different profit and loss ratio, and coupled with the holding mentality, the losing orders may have a hard stop loss of 100 points, while for profitable orders, you might only hold on for a profit of twenty or thirty points, and for a profit of fifty or sixty points, you would have to reduce most of your position. Seeing profits being given back and unrealized losses may also lead you to close profitable orders prematurely. This is loss aversion.
So how about this kind of psychological pressure? Actually, I think it’s best to start small at the beginning and gradually accumulate. This way, you won't feel particularly bad about the stop losses on the first few trades. For example, if you have 10,000 u and lose a few u, you won’t feel it at all. Losing a few dozen or a few hundred will hurt a lot more. The method of executing profits and losses with this low-volume doubling strategy is still to be studied and is currently being tested.
