I'm trying to create an exploration that will help me find stocks where the 50 MA has been flat for a period of time, say at least 10 bars, but price has moved quite a distance from the 50 MA.
What I can't figure out is how to create the code for the "relatively flat 50 MA" part.
Most indicators are tied to price, like volatility, so they don't work since I'm looking for price to have moved far from the MA, but the MA to still be flat.
I think the best approach may be something like the 50 MA hasn't moved more than "x"% from the 50 MA 10 bars ago. But can't figure out how to write that.
Anyone have any ideas pleas?

hey mmentors.... coding is not my strong suit, yet, but until something better comes along perhaps roc of the ma might work....h
ROC(Mov(C,50,S),10,%) < .25 AND ROC(Mov(C,50,S),10,%)> -.25

mmentors,
This logic should be relatively easy, following the guidance of the MS Users Manual?
A flat MA, meaning the value now is the same (or nearly the same) as 10 bars ago, plus or minus some percentage difference?
See if this works.....
--8<--------------------------------
ind:=Mov(C,50,S);
diff:=10 {percent};
lookback:=10;
ind < ((100+diff)/100)*Ref(ind,-lookback) AND ind > ((100-diff)/100)*Ref(ind,-lookback);
--8<--------------------------------
which, according to the MS Users Manual (and Hayseed) is the same as the ROC()....
--8<--------------------------------
ind:=Mov(C,50,S);
diff:=10 {percent};
lookback:=10;
ROC(ind,lookback,%)<diff and ROC(ind,lookback,%)>-diff;
--8<--------------------------------
It is truly amazing, the amount of information contained in that one guide!
Hope this helps
wabbit :D

Here's yet another way:
[code:1:370b60445e]{ user input }
i1:=Input("EMA periods",1,252,10);
i2:=Input("Lookback periods",0,100,1);
i3:=Input("Percent cutoff",0.1,10,2);
i4:=Input("Data Array (O=1 H=2 L=3 C=4 Typical=5)",1,5,5);
i4:=If(i3=1,O,If(i3=2,H,If(i3=3,L,If(i3=4,C,Typical()))));
{ calculations }
x:=mov(i4,i1,E);
y:=ref(x,-i2);
{ plot }
plot:=if(ABS(x-y)/x)*100 > i3,1,0);
Plot[/code:1:370b60445e]

Wow, what a great forum. 3 responses in a matter of a few hours. Amazing.
Thanks to all 3 of you. What you posted does exactly what I was looking for.
Interesting to see the different approaches too.
I'm new to MetaStock and it helps me to see how you more experienced users code things.
Thanks again.
