...was slightly confused about the counting back strategy utilised to determine the trend .
I use a 20 sma line intsead of a 50 with a 3/10/16 macd - should i be counting back 20 days to reconvene my medium line and what will that tell me for the next few days trading ?
The basic idea of the counting back thing, is useful if you think the trend line may change ie. It is flat at the moment, but you are wondering if it will go up, down or stay flat in the next few days.
You look back 20 days as you are using a 20 day average, and if you are not using daily charts, then replace the word 'days' with 'bars'.
OK, so an average is made up of all the prices in the range (20) then divided by 20, to give the average. This average is recalculated every day as a new day is added, and an old one - now 21 days ago is dropped from he equation.
IF, the price in the next few days remains at the same level ( it
might if the TL is flat) then we know that there will no no change in the calculation of the new days, the change in calculation will be from the ones dropping off the end.
OK, this is all pretty much guessing, but this is the way it goes.
We then look back 20 days as that is where the change in the calculation is going to happen. If we drop off higher numbers eg 20, 19 & 18 are higher than 17, 16 & 15 - then the TL will move down as the calculation will yield a lower figure.
I am not sure if I just clarified that or made it more muddy
Anyway, yes look back 20 days. If the last few days are higher than the next few then the TL should head down (providing as we guessed, the next few days are about constant).
The opposite is of course also true, if days 20, 19 & 18 are lower than 17, 16 & 15 then the TL should head up.
