Hi JG,

As you noted - 14 is the default on the RSI.

You can set it anyway you like (so long as you have the software).

Some short term traders set it at 2. That's a convention in that domain. Some traders extend it out to 21. That tends to be for medium term traders.

I find that 9 gives somewhat more extreme readings than the default of 14 and often better negative divergence readings - and quicker breaks of trend lines.

Same goes for the CCI. Default is 20. I use 14. I find it gives much more obvious negative divergence readings. I find that to be one of the most valuable indicators.

Bollinger Bands can be tweaked in a similar fashion. Bollinger himself suggests tightening up the settings for Bollinger Bands to get better short term readings. If you're a medium to long term trader, a setting with a median line of 50 (instead of 20) is recommended. Traders often use multiple Bollinger Bands to get a handle on short/medium/long term trends.

But, in the end, they're just indicators. Nothing more. They flash alerts. The action of the index/stock is paramount.
