For eg i want to know supports and resistances for intraday basis or at the end of the day for the next day. So u mean higher number more smoothness means less deviations and more accuracy. Can i use 50 SMA today was using it for the first time on NIFTY and it was working fine.
I am giving different DMAs for nifty as on today to make things a bit clearer.
1-Month DMA(22-DMA):4414
2-Month DMA(44-DMA):4315
3-Month DMA(66-DMA):4316
4-Month DMA(88-DMA):4474
5-Month DMA(110-DMA):4565
By choosing higher DMA the effect of old samples will be there.Shorter the DMA ,the effect of recent samples will be more pronounced.For trend line analysis better to have 100 or 200 DMA values.
Within the day also we can have SIMPLE AVERAGES for different periods 25,50 or 100 samples.Within the day I use 9-Exponential Moving Average.
