why do daily moving averages change in different time intervals for the same chart?

If I look at a 200 day moving average in a 3 month time interval, it will be one number for the present value, but if I look at it over a 2 year interval, it will be totally different for the present value. How is that possible? If the formula merely uses the 200 surrounding days to calculate the figure, shouldn't it be the same regardless for the present value if I'm looking at a 20 minute chart of a 20 year chart? The fuck?

It is FALSE that if you are looking at a 200 day moving average the number changes depending on how far back you extend the chart.
The number and line of the average is the exact same whether you make your chart view go back 200 days, 5 days, or a million days.

I noticed the same thing yesterday. Maybe it isn't days, but periods? So, if you go by day intervals, it figures 200 days, but if you go week intervals, it figures 200 weeks?

Take a screenshot of your chart and post here. I think maybe you are changing the candles from 200 days to something different?
A 200 day moving average is a 200dma is a 200dma is a 200dma. Never changes. All data is the same.

My Think or Swim platform from TDAmeritrade will only allow me to set X period moving averages. So on the daily chart, a 200 period moving average is a 200 day moving average, on a weekly chart, a 200 period moving average becomes the 200 week moving average (or 1000 day moving average, as there are 5 trading days per week, 200 * 5). If I want to see a 200 day moving average on my weekly chart, I will have to set a 40 period moving average for the weekly chart style set (40 * 5 = 200). I suspect many trading platforms are setup this way.
