My question is what time frame (calendar days or trading days) is taken into consideration by the major charting services (stockcharts.com, QT, etc.)... i think that they are taking into consideration only the trading days, but i cannot explain to myself why Williams (14) and RSI (14) are used as default... The only logical thing that is coming to mind is that this time frame (14) is accepted and is more a psychological number... |

essentially, it is nothing more than a time proven standard, somewhere between being "fast" and volitle, or "slow" and steady. for instance, the TRIX is really nothing more than a highly "smoothed" MACD, so it can be fast enough to be a good indicator, but the volitility has been removed.
