How to Get Daily Chart Data Under Realtime Chart

[topbadbady]

I'm coding some strategy which need 20 Day average Range Data or ARD(20). And the strategy applies to minute chart.

But I'm using TDAmeritrate Data Feed which only provide 20 Days minute data. So I cannot get ARD(20). coz we need at least 21 Daily Bar to get ARD(20)..

So I want to know how to get daily chart's data for my minute chart strategy.

You will then need to supplement your data with one of the data providers here that offers more data. http://www.ninjatrader-support.com/H...HistoricalData
