不要删除

你必须像我写的那样改变标志。

于是我就这么做了，它照样开到了五个合同。

发布OnTick()代码

MakarFX:

然后加起来，计算出这一时期的全部利润。

你又误解了。他说他想计算利润。该函数试图计算最后一个平仓订单的损失，结果并不正确。所以，他最后把所有人都弄糊涂了。

我这么一说，在两个合同上还是无限制的

Mihail Matkovskij 2021.08.02 19:46 #15608

MakarFX:
你自己说利润可能是负的，他想得到交易的总利润是正还是负的。

因此，只有当利润为正数时，才会将其加起来。如果是负数，就是亏损。如果我们想知道总利润，所有的利润，包括负的，都要加起来。而这个函数试图找出最后一笔订单的利润，它做得不正确，被称为lastloss。你不明白吗？哦，亲爱的...我已经筋疲力尽了...

Tretyakov Rostyslav 2021.08.02 19:47 #15609

Eugen8519:

我是这样说的，但在两个合同上还是没有限制。

不存在于无效的OnTick中

Valeriy Yastremskiy 2021.08.02 19:47 #15610

MakarFX:

然后加起来，计算出这一时期的全部利润。

"那你为什么要在利润上加上交换和佣金？鉴于

OrderProfit()

也可以是消极的...

而且，如果你只处理1个或几个匹配的订单，而不是全部，我们谈论的是什么样的总利润？"

有些东西真的让对方感到困惑。这句话说得很对，不是说负数的加减法)

我也不喜欢答案寻求，它就在那里)
