I wish to know if I am doing things correctly? I have read my MS users manuel P.186 on changing the MACD parameters but when it actually comes to it the MACD idicator only lets you change one number by right clicking on the idicator thats easy.Lets say for eg I want to change from 26-12-9 to 39-19-9 by changing that one number do the others automatically fall in line????????????? Regards PeterB

hey peter.... that changes the the signal/trigger line only.... perhaps you can adapt the code below to match your needs.....h macd style with inputs [color=blue:5c25ef581b]{ edited to reflect jose's more accurate numbers and investorretired's histogram suggestions}[/color]

ma1:=Input("short moving average",1,100,12.3); ma2:=Input("long moving average ",1,200,25.7); ma3:=Input("signal moving average",1,200,9); 0; a:=Mov(C ,ma1 ,E )- Mov(C ,ma2 ,E ); b:=Mov(a,ma3,E); a; b; a-b ----------------------------------------------

Any idea of how to add the MACD-histogram? :?

Hayseed: Changing a MACD to a histogram in MS will not get the desired results. This will give a histogram of the MACD or MACD signal line. I believe the MACD histogram is defined as the difference between the MACD line and the MACD signal line and then presented as a histogram. This makes the centerline crossovers and divergences easily identifiable. By changing your formula slightly (Listed Below “a;b” to “a-b”) and by then changing the line style to histogram will get the desired results. You may also want to add a horizontal line at zero. macd style with inputs -------------------------------------------- ma1:=Input("short moving average",1,100,12); ma2:=Input("long moving average ",1,200,26); ma3:=Input("signal moving average",1,200,9); a:=Mov(C ,ma1 ,E )- Mov(C ,ma2 ,E ); b:=Mov(a,ma3,E); a-b InvestorRetired

Metastock will allow you to use decimals in a moving average, but it will calculate the Moving average as if it were whole numbers. here is a test Macd 1 using decimals in the input ma1:=Input("short moving average",1,100,12.3); ma2:=Input("long moving average ",1,200,25.7); ma3:=Input("signal moving average",1,200,9); 0; a:=Mov(C ,ma1 ,E )- Mov(C ,ma2 ,E ); b:=Mov(a,ma3,E); a; b; a-b Macd 2 using only whole numbers ma1:=Input("short moving average",1,100,12); ma2:=Input("long moving average ",1,200,26); ma3:=Input("signal moving average",1,200,9); 0; a:=Mov(C ,ma1 ,E )- Mov(C ,ma2 ,E ); b:=Mov(a,ma3,E); a; b; a-b plot them into a chart and you will see that the numbers are the same

Hi Jose The plots are clearly different because one MA is using a whole number of 25 and the other is using a whole number of 26, not because MS is using the fractional component of the "periods" parameter. Regards Roy MetaStock Tips & Tools

Hmmm... I guess that MetaStock's standard MA functions truncate inputs to integer values. This works: [code:1:452bc7b3dd] ma1:=Input("short moving average",1,100,12.3); ma2:=Input("long moving average ",1,200,25.7); ma3:=Input("signal moving average",1,200,9); Ema1:=C*2/(ma1+1)+PREV*(1-2/(ma1+1)); Ema2:=C*2/(ma2+1)+PREV*(1-2/(ma2+1)); a:=Ema1-Ema2; b:=Mov(a,ma3,E); a;b;a-b [/code:1:452bc7b3dd] jose '-)

It's a precision thing, not a method thing... :)
