great content, Cameron. So many facets to this diamond, TOS. Thanks for your enlightenment

[@tradertalkswebcasts]

Glad you enjoyed it! And it's always my pleasure. ^CM

[@Rob-on-the-go]

Awesome info! Thanks!

[@tradertalkswebcasts]

Certainly my pleasure! ^CM

[@liaoweien]

thanks for the content. For the thinkback or ondemand feature, is it tick by tick or min by min or day by day for the data granularity? Thanks in advance.

[@tradertalkswebcasts]

OnDemand data is tick-by-tick for stocks, futures, and options. Enjoy! ^CM

Is there a way to backtest using the Web version as opposed to the desktop version?

[@tradertalkswebcasts]

The backtesting tools I demonstrated here are only available on the desktop version. I hope this helps, and thanks for watching! ^CM

[@scotthirsch3479]

Another question: say you like how the back test looks so you build a custom scanner off the features. What about the ability to forward test the results of a scanner to see how the results do over say a week or two? This would be a logical follow up to back testing since presumably one wouldn't buy all the results of a scanner. If you can't do that, maybe there are some tricks to make it more manageable. Thanks!

[@tradertalkswebcasts]

I'm not aware of any current functionality that would allow for this process to be automated, beyond waiting a couple weeks and re-conducting the scan. In any event, thanks for watching! ^CM

Thanks for this, very helpful. I tried Thinkback though and found ticker prices were often incorrect, sometimes repeating the same data on consecutive trading days. I’ve also found other comments wit this issue. Is there a fix for this?

[@tradertalkswebcasts]

Happy to clarify! When the data repeats, that's not an error but instead reflects a weekend, when normal-trading-hours prices don't change. I hope this helps, and thanks for watching! ^CM

[@DAH-zr4cm]

Thanks for responding. But on my system I’m finding that April 1 and April 2 prices are the same, but they weren’t in fact identical. Found this for LEVI and others. I’m wondering if there’s something I’m missing. Meanwhile, thanks for the outstanding classes.

[@stancartmankenny]

does this include intra-day data?

[@tradertalkswebcasts]

Yes, thinkorswim Desktop's OnDemand feature includes tick-by-tick, intraday data. Enjoy! ^CM

[@melleatherman3181]

can you back test a strategy that does not take and trades?

[@tradertalkswebcasts]

I'm happy to help, but I'm not sure I follow your question. Would you mind clarifying? Thanks! ^CM

[@scotthirsch3479]

How can I use 4 hour charts etc with the daily when doing back tests without losing my place in time? You end up seeing everything by having to scroll back which defeats the purpose.

[@tradertalkswebcasts]

I know exactly what you mean. One way to randomize this view is to load a long-term four-hour chart, quickly zoom in on just the last two weeks or so, then use the scroll bar at the bottom to zip backward in time to a random spot on the chart. You may have some inclination of general movements of the chart, but you won't be able to recall enough detail to influence your testing. I hope this helps, and thanks for watching! ^CM

it is not placing order in onDemand Virtual order instead putting it in back trades
