RSI for Stock, ETF or Mutual Strength

Post by j2sailor » Mon Feb 16, 2004 6:30 pm

:?: Hi. I'm reading up on using a 14 and 21 day RSI. Anyone had experience with using 14 day RSI for timing short term reversals (trend reversals when RSI falls below 30) and 21 day RSI for trend strength? Any help for this Neophyte would be appreciated. :)

The technique you mention sounds non-robust.

Yes, by itself it would be quite non-robust. I am looking at this as another tool to add to the arsenal - not a lone indicator by any means. I have very limited funds and am trying to find effective entry/exit tools to use for ETF or Mutual funds. Any advice would be welcome. Thanks again for taking the time to reply :)

I use RSI(21) in this manner: When the indicator is running along the 50 line, it just confirms for me that the stock is consolidating. Anything above 50 lets me know the stock is closing higher. I don't use it for OS/OB, turning points or trend strength. But I think the question you need to ask yourself is, "why use 14?" and "why use 21"?

Those parameters are almost identical and produce indistinguishable results. The 14-day is barely sharper. Conversely, the 21-day is barely smoother.

With the parameters of 14-day and 21-day in mind, one RSI functions in a similar manner relative to the use of both.

For an illustrative example, there's an attached PNG file which exhibits the uncanny resemblance shared by a 14-day and 21-day RSI.
