我创建了一个EA交易，可以计算一些条件，并为每个条件提供多头或空头价值（+或-0.1手），然后将所有条件相加，得出净多头或空头头寸。
然后它应该要么开一个新订单，要么关闭一个未平仓订单，以改变先前的未平仓头寸（仓位），以匹配交易条件根据每个新柱的变化计算出的目标值（总和）；这是通过使用ontick函数完成的。
如果我仅使用一个或两个条件，则可以正常工作，但是当我增加条件数量（总和可以大于0.2手或小于-0.2手）时，它会以1的价格进行交易，然后平仓应该然后再进行一次过度交易，这不应该进入一个令人讨厌的循环。
我不明白为什么它可以在两个条件下完美地工作，但不能在两个以上的条件下正常工作。我想知道是否有人对任何输入表示感谢。
这是我第一次尝试EA，最好的问候是Ken。
