If I created an indicator that counts # of times a event occurred in the one minute time frame. And added the indicator on the chart. What is the length of historical data that will be used to calculate the # of times the event happened.
For example
If the event occurred 10 times in the last 5 days, and I added the indicator on one minute chart.. Will my output be 10? In this example the indicator was able to look back on 5 days worth of data. So my question is.. How far back does the indicator look to calculate for:
1 min
2min
5
10
1hr
2hr
Is there a PDF out there that tells this info?
What if instead of adding it to a chart, I added this to my watch list; will it then be able to look back on a longer length of historical data?
I've heard that tS only stores 30 day worth of 1 min data?
Ideally I would want to run this indicator on the entire universe of stocks to get my output calculation for this event and make my trading decision. In an ideal world I would get the 1 min data on every single live stock out there... Plug it in a data base and do my calculation. But that would be costly to get historical tick data on all stocks. TS data is free and that's why I'm asking this question. What is the look back length for TS indicator calculation for minute bars?
Thx
Can you help answer these questions from other members on NexusFi?
Tradestation can go back several years of 1 minute data and your indicator can calculate on all data that is on the chart. As a rule of thumb, you can get more history for higher timeframes: weekly > daily > minutes > tick data.
Regarding your example when you have 10 events over 5 days (on 10 different bars) your indicator should return 10 as a result.
Thank you for the reply, i feel like i'm making this complicated for myself but want to make sure before I start working on my project (previously I spent 6 months programming on NT and ran into a major technology related issue)
Regarding that point you made- on a 1 min chart, you will never be able to scroll and view 1 year worth of data on the same chart (at least that is what I have experience with most trading softwares).
to be clear, on 5 days 1 min bars.. the event occurred 10 times; the output today should be 10. but my goal is to be able to (like you said TS can look back several years worth of 1 min data) lookback 1 year worth of 1 min data (that obviously wont be displayed on 1 chart so I would have to add the indicator to my watchlist?)
another example
i want to be able to count a cross between price and an indicator on 1 min chart for the past 1 year.
in TS;
if i add this indicator that counts crosses on chart; the calculation would be the max length of 1 min data the chart can display. on most trading software max length is 5-10 days.
if i add this indicator as a variable (similar to last, bid, %change) to my watchlist; will the max length calculating the # of crosses be max length of historical data that tradestation has?
in Tradestation it's not a problem to load 1 year or more of 1 minute data on a chart and scroll through it. For Radardscreen or the scanner, your study will work on the data you load. So if you load one year back, it will use this.
