What is the difference between these 2 variables from a US market perspective?

Hi,

What is the difference between the following from a US market data perspective:-

Low[1] and Bars.GetDayBar(1).Low
High[1] and Bars.GetDayBar(1).High
Close[2] and Bars.GetDayBar(2).Close
Open[0] and CurrentDayOHL().CurrentOpen[0]

The variables seem to differ in value and hence my values in my indicator seem to differ as well

Low[1] is the previous bar's value of whatever time frame you have on the chart (or host window such as Market Analyzer). This is subject to the Trading Hours you have selected for intraday bars, so it is quite likely you could get a previous bar's set of OHLC values different from the previous entire session's values.

Hi Bruce,

Thanks for your reply.
I was using Low[1] on daily charts and Bars.GetDayBar(1).Low on intraday charts.

My intraday chart hours are regular trading hours. Could that be the reason? How do I get regular trading hour values on a daily chart?

Yes. Most likely you will find that your daily bars are ETH. To get regular trading hours on a daily chart try instead making it a minute bar chart (1440 minutes, which is a full 24-hour period) and then picking the trading hours from the dropdown that you want to use. It won't include all 24 hours - only the times included in your trading hours. In this way, you can make a daily bar chart of any trading hours.

This is where the data provider is an issue. If I pulled 1440 min bar for 365 days with TWS, that will take forever to load. I had that problem at 240 min bars. It was a nightmare!

Yes, Interactive Brokers is not a suitable data feed. You'll want to pick up a paid data feed if you're going to be working with a lot of data. IB's data is okay for real-time usage, assuming they have what you need, but they do not really want to be in the historical data business so they only provide historical data with a lot of limits, including pacing and limited lookback, and these limits make them hard to use as a sole source for historical data if you're back-testing for doing research that involves looking very far back, or if you need historical data for a lot of instruments.
