moving average does not mean that it has to be exact ... it is a prevailing market movement not coming in the market ... You can only Gues through EMA 200 ... BUT for good results ... give three times the EMA Value ... 200 100 and 50 if both of them cross the line then you will know about the market ... and can give orders, and moving averages are good filters The main reason for choosing other forms of MA (EMA, HMA etc.) is to reduce lag. With a 200 day EMA in place, you will get a buy / sell signal around 30-40 ticks before the SMA on the chart. If you want to identify a reversal, use HMA (moving average of the hull) where the lag is almost zero. Always use 'close'.
