1 minutes bars for 250 symbols.

[nedibe]

Hi Robi,

I'm downloading 1 Minute history for 250 symbols. Since I can't download them at the same time, I have to download the history one by one.

So I was first downloading my symbol in a loop one by one, something like the last 9 bars for each of them, it took ~2 seconds to download the 250 stocks. The fisrt time it takes ~2.5 minutes but I don't care since I do it only once.

So it was working well but something got my attention, after a while : the volume was wrong.

I investigated this issue and found out that I needed to clear the symbol cache after each download in order to correct the 1 minute ticks. My problem now is that after the call to clearsymbolcache, downloading the 250 symbols takes ~2.5 minutes.

How can I speed things up and get correct data??

Thanks,
Nick.

You should only be downloading the 1 minute bars once and then use the quotes to update the bars within your application. You will not have any issues if you change your program logic.

Thanks for your response robbi,

But to recreate the 1m history with the quote, I need the exact time. I need also to know if it's a trade and the volume.

But it looks more and more like a time and sales...

Thanks,
Nick.
