The same physics applies. The higher the frequency cutoff of the filter, the less group delay. The less group delay a filter has, the less attenuation ability. A lot of people over the years have written about Kalman filters in finance. A Kalman filter is really an estimator rather than a traditional digital filter. However, no matter what flavor of Kalman filter you use, they don't really seem to perform any better than digital filters. That is because you need to understand the distribution of the statistics of the process you are dealing with. Financial time series have a much more complex underlying process than say a satellite orbiting the earth.
I trade on the 5 or 15 minute charts with the the daily moving averages displayed on it. Look at how Tesla tried to hold above its 200-Day @$217 until 10/25 @115pm when it finally collapsed. It couldn't do it. The RSI was indicating weakness.
Ditto. I illustrated the 50, 100, 200 MAs because those are the most commonly followed. However over any particular time, one can try different periods to see if one fits better than others.
There is only 1 MA that is rarely used but of true value: a MA that indicates trends in volume. I leave it up to you to find out how that is of use
Check out ROC RateofChange as opposed to a MA especially one as long as 200 for intra day. No averaging, although I plot an MA of the ROC, which is very secondary. Entry and exits are both earlier. Also did you note where the 200 MA was from the 18th to 23rd? For 5 days it was MIA.
. I have struggled to formulate good rules for using ROC indicators that would allow them to be incorporated into new or existing trading systems. I believe the classical approach was to take buy signals when the ROC line is above its center line and take sell signals when it is below. However, prices often go down for a long time while it's above or go up for a long time while it is below... What do you think is the best way to use this type of indicator?
Love to see one example where the hard right edge isnt way after the fact... Everything is crystal clear in hindsight as the scaling and patterns are much neater
