请问如何让指标的运算和图表保持同步？谢谢，功力不够，想不到应该如何再改了

Indicator always slower then 初学者的问题 MQL5 MT5 MetaTrader 如何把Lab3Buffer[i]画出来一条直线

rates_total :总K线数

prev_calculated:为指标计算赋值过的K线

谢谢，但情况没有改变，仍然不能实时的和图表同步我每次要重启这个指标才出现同一刻

需要初始化

不错

指标的底层原理是每次新柱产生进行一次收线柱计算，所以Tick实时更新在目前框架下没法实现，除非重写一个类，但显示在逻辑上也存在问题，当前柱的连线会不断变化位置，需要精密的逻辑设计
