I'm playing with EL on a MC trial at the moment and don't have my hands on TS in order to find out for myself.

In MC, you can use symbol_close, symbol_high etc to access all bar data (useful when an indicator is being calculated on historical prices). Does TradeStation have the equivalent keywords / functions to access all price data currently available or are you always restricted to the current bar data and already processed bar data?

Thanks!

I am currently modifying my code ... I got my hands on TS since my first post and so far it seems like there isn't an equivalent.

Anyways, what I was doing was drawing S/R lines ... except, I only draw what was resistance below and what was support above (below and above relative to the most current close on the chart). My original code did this as each bar was processed since I knew what the most current (a.k.a future most) bars close is at all times ... now, I (am going to) simply draw in all S/R lines and once I am on the last bar, I will go back and erase all S/R lines that don't fit the criterion specified earlier.
