Comparing bar size

[2014Michael]

Hello, I have a question. I want to compare size of current bar (High [0] – Low [0]) to the size of a previous bar, so it will be possible to condition like ‘open position when current bar longer than previous by 2 ticks’ (I have other conditions, determine what position, long or short). Could you please help me to code this? Thank you

Hello 2014Michael,

Price series use a BarsAgo index.

For example Close[0] is the close of the most recently updated bar. Close[1] is the close of the previous bar.

To compare the high of the previous bar to be greater than the current bar would be High[1] > High[0].

Hello Chelsea B. thank you for responding. I'm actually did NOT ask how to compare High [1] and High [0]. The question was about how to compare size of a current bar to the size of a previous bar (I'm using OHLC bars). Would be great to know coding

Hello 2014Michael,

This was just an example to show how to use barsAgo. You can subtract the low from the high, or do any calculations you would like to do with the values from the Open, High, Low, Close, and Volume series using BarsAgo indexes.

Hello Chelsea B. Could you please give me an example of code of how to compare size of current BAR to the size of a previous Bar? Thank you

Hello 2014Michael,

What do you consider the bar size?

Are you asking for the volume?

Are you asking for the visual width of the bar?

Are you asking about the High[0] - Low[0]?

How do you want to compare the values? Greater than, less than? equal to?

Hello Chelea B. Thank you for helping. I'm asking how in code to compare High [0] - Low [0] to High [1] - Low [1] (this is what I meant by size of current bar to size of previous bar). Only this, no volume, no width. Then in condition I would say 'When current bar size bigger than previous bar size by x number of ticks, open position.

Hello 2014Michael,

int TicksExceeded = 4;

if (High[0] - Low[0] > High[1] - Low[1] + TicksExceeded * TickSize)
