I have been reading your MultiCharts help as fast as possible.
I think I have figure out how to do the two items below;
1/ Get bollinger band and RSI data out to MS-Access for all charts
(1min, 5min, 10,15,30,60,DB,WB=WeeklyBars).
2/ Not have to adjust the bands in more than one place.
I think I was misled by the TS User on the Omega-list.
He said I had to set up a MultiData chart to get the data out.
From reading your manual here is the approach I think will work.
To come to this conclusion I noticed that there is a check box under "Study properties" called "Update on Every Tick". That was the key. Here is my assumption and method. I am assuming that since the band values are being totally calculated from that script, that I can get the file append command into a copy of the bands script called "Bollinger Bands John" and it will be run every tick.
Here is the remainder of the method.
1/ Put the file append command in the Bollinger band script on every chart (1,5,10,15,30,60,DB,WB) and write out the values to 1 file for each chart. I will be sending out the 3 band values (upper, middle lower) and the RSI value. So I will have 8 charts and thus 8 files. I will also include the last price from the 1-minute bar chart, which will contain this (last price, RSI, Upper Band, Middle Band, Lower Band). So this is the key to not having to update the bands from a special MultiData Chart. I thought I had to have a special chart to get the data out from the 15-minute bar chart on every tick. I guess I do not have to do this. If I want to slow down the writing to the file I think there is a second’s timer in EasyLanuage I could use to only write every second (or whatever) rather than every tick. It has been 10 years since I used TS 4.0 end of day. I will probably be through the EL manuals in a week or two. Combine an apple and a coffee after a good nights sleep and a light breakfast and the mind for reading is hyper alert with lots of ideas flowing (see if this one is any good).
2/ My MS-Access program now will pick up the data from these 8 files every second and I am all set to go.
Please let me know if this will work. If you are too slow to get back to me I may find out later today or tomorrow.
Think I figured it out. Maybe you can review my assumptions.

Maybe my explaination was poor. I don't want the raw data sent to MS-Access. I want the final calculated values of the bands (upper, middle and lower) sent out to access based upon whatever adjustments to the bollinger bands I have made. I agree, there is no need to make these calculations in MS-Access. However what I am doing with these calculated values in MS-Access is another thing all together and is tied directly to my trading strategy.
