Intra-day historical charting sources?

[Trader61]

I have an IB and TDAmeritrade account. IB has pretty good intra-day info but only up to the last month. I'm having trouble connecting NinjaTrader to TD. That's in another post. Yahoo.com has really good historical daily chart info. But it doesn't seem to provide any intra-day data.

Is there another source people can recommend for historical intra-day data for NinjaTrader charts?

Hi Trader 61,

You can view the offerings of NinjaTrader data providers at the following link.

However, I can not recommend a specific provider, but any of the providers of historical tick data will be able to handle the intra-day periods.
