saving quotes to file at each new bar

[daglas]

Dear friends.
I want to export bars from the chart to file on each bar update.
I get one source from member of this forum and try to change it for live saving data.
But unfortunately this strategy insert into file 01.01.1800 0:00:00,0,0,0,0 at each row, and I want to see OHCL data at this file, like 0.012652;0.012645;0.01265;0.012652;18.07.2011 1:01:00.
I attached file with source.

Hello daglas, I would suggest you take a look into this sample we published here :

It would use C# 's System IO to write the bars data to a text file, you could also add the bars time (Time[0]) to the saved strings.

it's a perfect code, thx very much. But how can I reduce length of history data. For exemple I want to save only last 100 candles data. Or if it be more simple to save only today data?

Daglas,

You could add date/time checks for this. Here is an example that checks date equality with the bar's time stamp and your computer clock.

if (Time[0].Date == DateTime.Now.Date) { }

Last 100 bars would be something like:
if (CurrentBar > Bars.Count - 100) { }

Ok, thanks. It's perfect.
