听着，人们总是在谈论风险回报，但真正让你留在市场中的是头寸规模。你交易的是差价合约，这意味着杠杆。太多人随意选择头寸规模，然后在一次正常回调中就被清仓了。
这里有一个更好的方法：决定你愿意每笔交易损失多少资金（比如，1-2%）。然后，确定你特定设置的止损距离——是50点，还是100点？一旦你有了这些，你就可以精确计算你可以开多少手合约。例如，如果你在1万美元的账户中承担1%的风险（100美元），并且你的止损距离是10点，那么你只能开10个单位。这对于长期生存来说是不可协商的。这无关乎你是否经常正确；而在于当你犯错时，不会是灾难性的错误。
Completely agree. It's the practical application of risk management that separates long-term traders from those who blow up accounts. Do you factor in the margin requirement for CFD trades into that 1-2% calculation, or is it purely based on potential capital loss?
While the 1-2% rule is standard, applying it rigorously with CFDs and their inherent leverage often means needing to adjust that percentage or tighten stops considerably to avoid outsized losses, even on small moves. It's not just about the per trade loss, but the actual capital at risk.
