Analyst Days Since Last Rating

This function utilizes the historical analyst buy/sell recommendations, downloadable from yahoo by Yahoo Historical Buy/Sell Recommendations, to determine how long it has been since an analyst rating has been provided for a stock. This function can be useful in trading algorithms in determining a confidence value for the rating (the longer its been, the lower the confidence). It can also be used to check to see if too much time has past and you no longer wish to consider using the analyst rating.


The function takes two parameters. The first is the symbol you would like to see the ratings for. To specify the current symbol, just enter "". The second parameter is the rating firm for which you wish to see the rating. Use "" to use all rating firms.

If the symbol has not yet been rated, the function will return -1.

To chart the function, you can use a formula like:

Plot(AnalystDaysSinceLastRating("", ""), "Days Since Last Rating", colorBlue, ChartLine, StyleOwnScale);

This will plot the number of bars that have past since the symbol was last rated.

If you find a useful way to use this data, I would love to hear about it! If you have suggestions for improving the function I would love to hear about that as well.
