MQL4 为什么我在 OrderModify 上收到错误 130，因为我的 SL 应该是完美的？

Question

谁能告诉我为什么 SL 没有移动，我收到错误 130（ERR_INVALID_STOPS，无效止损）并且我运行了 Print("Minimum Stop Level=", minstoplevel, " points" );在我的代码中并得到“10”并尝试运行代码，即使是 11 并且仍然存在相同的错误。

有人可以看看并告诉我，我几乎没有任何头发可以尝试所有的可能性。

非常感谢

您的 newSL 变量应该是 double 类型，而不是 int。

此外，当您发送类型为OP_SELL 的订单时，请使用Bid 价格而不是Ask。

Docs:

市价单开盘时（OP_SELL 或 OP_BUY），只有最新的 Bid（卖出）或 Ask（买入）的价格可以作为开盘价使用 价格。
