multi data series

Postby lawrence124 » 01 Nov 2012

hi, i added a 3 minutes data series to a chart, and i used RSI(c of data2, 14,...) on it, the value is different from the RSI i used on a single series chart
to clarify it, seems like the RSI(c of data2, 14,...) values change when the time frame of data1 change (ie, using 10 seconds instead of 30 seconds)
any setting that i've missed? Thanks

ps, the 3 minutes RSI would be correct if i set "Base Study On" to series #2, but can i do that for signals ? because, say, i use RSI(c of data2) > 70 = buy, then, the signal generation will be different from the chart

One easy way to do this then would be to add 1 for every 4th bar you see in data series 1.

What do you mean when you say "I'm in data2"?

It's my understanding that the EL code is run (1) after every tick on data1 if the study's "Update On Every Tick" property is checked or (2) at the close of every bar on data1 if the property is not checked. When the code is run, you can check both data1 and data2. You're not "in" one or another.

You may want to see if it is possible to check the BarStatus of data2 to indicate whether that bar is completed and then update your counter appropriately.

Good luck!
