Addressing History Values by datapoint as well as time

[sniffer66]

I guess my +1 doesnt count but I'll chuck it in anyway

Will benefit anyone who wants to do a lookup on any milestone based event in a market. As well as tennis I'm thinking, since a goal in football...

I'd like to put forward a suggestion to be able to refer to values in a History List by the number of data points ago, as well as being able to select time in secs/mins

I was just trying to figure out how to reference previous ticks to more accurately identify price movement and found this thread when searching.

What I'm wondering is if it is possible to reference the bars on the chart of the ladder screen. ie. price 2 bars ago was higher than price 1 bar ago. I believe this is similar if not the same sort of thing. Referencing based on event rather than time.

Is the data that produces the in ladder chart accessible for use in rules or could it be possible?
