Thank you for your help...this is pretty close to what I want to do, but instead of writing history for each bar of one ticker, I basically want to print "Ticker, Date, Close, Support, Resistance". I almost want to replicate what is shown in the exploration results. For example:
ChartNo = 1000;
support1 = Study("SU",ChartNo);
support2 = Study("S2",ChartNo);
resistance1 = Study("RE",ChartNo);
resistance2 = Study("R2",ChartNo);
Filter = C > 0;
AddColumn(Close,"Close");
AddColumn(support1,"Support1");
AddColumn(support2,"Support2");
AddColumn(resistance1,"Resistance1");
AddColumn(resistance2,"Resistance2");
When I hit explore on a given watchlist or sector or whatever, for n=1, what prints in the exploration results is exactly what I want written to a csv file. So one file with multiple tickers and the fields for each ticker. Thanks again.

Ideally, whenever I draw a trendline on a chart, I would like the data to be written to a text file (or I can batch it EOD) so that I can have another application parse the file to get daily trendline levels for each ticker. Currently, I can run a scan on anything that I tag "RE" or "SU" to get trendline breaks, so that data is stored somewhere, I just don't know if/how I can access it and if there is a way to setup a process that auto writes it to a file. Anyone know how I can set this up? Thanks.
