The EMA's are because you advised them
I'm curious what you are doing with them, but I respect it you are taking this thread slowly.
I haven't really looked at them yet, but will do it soon.
Most traders use moving averages in one way or another but I never had much of an affinity to any particular one. From time to time I would put different moving averages or combinations of them on my chart and see where price was trading in relation to them but as far as I remember there was never any consistency in my use of them.
However, last year I was day trading a strategy on 5m bars that was based on my close observation of the market. The essence of the strategy was to wait for momentum in the form of a sharp move up or down and then wait for a natural retracement and take a position. I did this by looking only at the price action itself (relative lows and highs) and did not use anything else to help me define an entry point.
This strategy had an excellent win/loss ratio. Infact when I first started I had a string of consistent wins but it was eventually undone by the fact that my stops were placed too far away from my entry resulting in a losing trade taking the profit that was gained from several winners.
A long time after I abandoned this strategy, I came across a system over on FF that used moving averages to define an entry into the trend after the period of natural retracement.
The premise of the system, which was created by Phil Nel and based on the 5m timeframe, is that when the 50 SMA is sloping at an angle of 20-30 degrees, price will pull back into the zone of the 10 and 21 EMA and it is then that an entry should be taken.
When I read this thread I started looking at these moving averages across all timeframes and saw that time and time again the price would act in the same way whether it was the 5m, the hourly, the four hourly or the daily and upwards.
I have never traded this system mechanically (Nel gives fixed stops and targets) but I have always kept these moving averages on my charts and base a lot of my trades around them. (it is worth noting that I changed the 50 SMA from the original strategy to a 50 EMA)
They are certainly not NECESSARY to trading price action successfully but they really help me personally understand the rhythm of the market.
I have attached a chart of the same market and TF that Raes posted earlier - the AEX index on the 1hr timeframe. It illustrates this rhythm well.
