Just this morning, I ran some of my scans manually and they produced results but my alerts for the same scans have not sent a notification this morning. This is the first time that I noticed this happening. I have sent the question to SC but I don't think that they will respond. Have you guys got any idea what I may be doing wrong ?
As I've said, I don't use alerts, but I think I recall that if the alert condition is already true when the alert is activated, you don't get an alert - the condition has to become true - i.e. the status has to change from false to true to trigger the alert. If it's already true it doesn't. That's different from a scan, where the condition has to be true at the moment to get picked up in the results.
But maybe someone who actually uses alerts can chime in.
Change your Stockcharts password in case someone has guessed it.
I find alerts to be hit and miss. I have one that is supposed to trigger every hour, but it only sends results once a day and it often has some inaccurate results from my review, but..... it could be a spike data point that triggers it and then it doesn't pick up anything new that meets the criteria that day. I don't know.
Most of my alerts (and scans) are PnF related and the charts are constructed differently than time based charts but the one that I'm less than impressed with is one that is looking at ROC(2).
So I'll have a chart saved into a watchlist and then upon reviewing it days or weeks or months later, it's not the same chart as it was when I added it to the watchlist. That sort of thing happens to me. Not a lot, but it happens.
All you need to do it change a high or low price in a column reversal area to potentially change the appearance of the chart. Or a data adjustment, like dividends that may get inserted into the data well after the fact.
It appears that they presort it so that the ones that moved the most "today" make the list that is sent. So it is basically dominated by low priced issues most of the time. And I would assume things that moved from open of trading to when they send the report. Not a very useful report. I've mentioned this to them and they are aware of the limitation.
TD Ameritrade has a "Portfolio Planner" tool. This tool mischaracterizes and/or ignores the investments in the portfolio it's "analyzing". So it may or is only looking at portfolio positions that match what the programmers have listed in their accepted positions for classifications but displays such pretty pie charts. So this means that you can have a 100k portfolio, for example, and only 50k is being classified and used in the planner tool. It's not like they don't have a classification available for everything. Just somethings are not recognized as being accepted in the planner tool. I've mentioned this to them and they are aware of the limitation.
Now, they don't disclose any of this. You have to find it, and be aware of it. They'll fix it, if or when they get around to working on that area of the system. Very similar to the responses that I get from StockCharts.com when talking about errors and omissions. They'll address it if or when they get around to working on that.
"Percentage change calculations are based on a projected volume figure.
The projected volume of a stock is based on the total number of shares traded and the time of day. After the market close, this data item is updated using reported closing volume numbers."
StockCharts.com has added a filter like this called RVOL which stands for Relative Volume. You can put in a time parameter and it will compare the current volume to the moving average you put in for the parameter.
Although you can only "see" the RVOL indicator in ACP, you can use it, and several other ACP only indicators on the Scan and Alert workbenches.
