问题描述
我想计算每秒的价格变动数(或价格变动).不幸的是，MQL5的 ENUM_TIMEFRAMES 只能保留1分钟. 此指标证明有可能，但是如何?也许通过 OnTimer事件?
I would like to calculate the number of ticks (or alternatively the price change) per second. Unfortunately MQL5's ENUM_TIMEFRAMES only goes down to 1 min. This indicator proves it's possible, though, but how? Maybe by means of the OnTimer event?
非常感谢您的回答！
推荐答案
datetime时间是自新计算机时代以来的秒数.如果您调用返回datetime的TimeCurrent()，它将为您提供整数.如果您在0.1秒内再次调用它，您将收到相同的整数(或same + 1).指标可以计算OnCalculate()中的滴答数，并与以前的时间进行比较.像这样的东西:
datetime time is number of seconds since the new computer era. if you call TimeCurrent() that returns datetime, it will give you integer. if you call it again in 0.1 second, you will receive same integer (or same+1). The indicator may count number of ticks in OnCalculate() and comparing with old time.something like this:
datetime lastTime;
int ticksLastSecond;
OnCalculate(***){
if(TimeCurrent()>lastTime){
lastTime=TimeCurrent();ticksLastSecond=1;
}else{ticksLastSecond++;}
}
如有必要，将一个数组中的ticksLastSecond添加到最后一分钟或任何其他时间段的平均值
if necessary, add ticksLastSecond in an array to average over last minute or any other period
