我的问题是:在指标编写过程中需要使用iBands 函数中的 applied_price 参数里调用 Previous Indicator's Data 价格类型,但是applied_price 参数里没有对应的

Previous Indicator's Data 价格类型,我该怎么调用,或者模拟有Previous Indicator's Data 价格类型的布林线,希望大家可以帮助我。

iBands(NULL,0,20,2,0,,MODE_LOWER,0)

You must make double array with values of indicator from you want to get iBands() and then apply to this array function iBandOnArray(). For example see RSI_BANDS_MA:
