Fix ThinkorSwim Delayed Alerts and Notifications

Is anyone noticing delays with scan alerts? Sometimes it's several minutes long. As a day trader, getting an alert a few minutes late could mean you miss an entry. I'm using SMA's, EMA's, VWAP, LinearRegReversal and LinearRegressionSlope in my scan, but it doesn't really matter what studies I use, I oftentimes get delays on desktop and mobile.

I reached out to Support and I keep getting different answers. Some reps are saying that there shouldn't be a delay. Then some reps say that the delay is 5 minutes. I don't know who or what to believe. I'm considering using trade ideas for alerts, but that would be a huge waste of money.

That is known, or at least to me, and I have been telling people that. The only way that you can get real-time scan results is by clicking that Scan button whenever you want to see new result.

I stopped using the scanner watchlist because of this problem. Usually between 3-5 mins. Sometimes I get the results in real-time though, but that is rare. An alternative solution to this is by adding a set of alerts into your code. As soon as the signal appears you will get notified. This solution will not work if you want to find new stocks from a basket of watchlists.
 
What do you mean by this "An alternative solution to this is by adding a set of alerts into your code." What exactly are you adding to thinkscript to get alerts in real-time?

"This solution will not work if you want to find new stocks from a basket of watchlists." Are you saying that you can't get real-time scan alerts from a watchlist of stocks and You can only get real-time results when scanning all stocks?

@GetRichOrDieTrying With the Alert() function added to your indicator, you will get notified of new signals in real-time. But the catch is that you must be viewing that chart (or at least have it in the background). This does not work for when you try to find new stocks because imagine loading up 100s of different stocks and have them run in the background. Will likely to break your ToS.

I am familiar with scanner setup and am using it for quite some time. Now, I just want to DYNAMICALLY populate the result of a scan into a watchlist. Easy, I would go to watchlist and select the name of the scan that I previously saved. it seems obvious.

The problem is that the result I see in watchlist is not updated. It means that when I go back to scanner and hit scan button, the result is different than what the watchlist gave....What did I do wrong? why the content of watchlist do not reflect the result of the scanner? do I mess up with timeframe (in my particular example, I have it set to one hour)

@BenTen Ah just simple as that? I guess this is the case for every timeframe of any scan? That would also mean that for short timeframe scan, we might have results that will never show up in watch list if the scan was below the 5 min timeframe then.

@moutic777 We don't know for sure the exact delay period. But we estimate that it's between 3-5 mins. Sometimes the result may pop up in real-time.
I see. If I understand correctly, this means that the watchlist should not really be used as a visual alert/notification....that a proper scan alert must be set in order to be notified when the event actually happen. That would be great if TOS could improve it and make the scan-result-watchlist real time.

I spoke to ThinkorSwim today asking them about their watch lists they don't update in the morning for 5 to 10 minutes is there a service out there that their watch list instantaneously updates that allows you to use scripts for ThinkorSwim? Thanks in advance

@moutic777 Alerts set directly on your charts are real-time. Not sure if it's the same elsewhere.
No watch list columns are delayed 5 to 10 mins . I have a watch list column that alerts me to stocks that have gapped outside Bollinger bands and start heading back inside the bands perfect example was Pinterest today but I missed the whole move because of the delay in the watch list columns
