I am looking for a good indicator(s) that detects trending (or lack thereof) on a Daily chart. Could someone point a few decent ones.

Thanks

Maybe soeone could take a look at this, see if it worth the conversion

Inputs : SMAfast(7),SMAslow(65),LoTrigger(-0.3),HiTrigger(0.3);
Variables : shift(0), MAType(1), cnt(0), loopbegin(0), first(True), prevbars(0);
Variables : sum(0), smconst(0), prev(0), weight(0), linear(0);
Variables : MAValue(0), MAstring("");
var: signal(0),noise(0),efRatio(0),i(0), Fastest(0.6667), Slowest(0.0645);
SetLoopCount(0);
// initial checkings
// check for additional bars loading or total reloading
If Bars < prevbars Or Bars-prevbars>1 Then first = True;
prevbars = Bars;
If first Then Begin
// loopbegin prevent couning of counted bars exclude current
loopbegin = Bars-SMAslow-1;
If loopbegin < 0 Then Exit; // not enough bars for counting
first = False;
End;

// moving average
loopbegin = loopbegin+1; // current bar is to be recounted too
For shift = loopbegin Downto 0 Begin
MAValue = 100 * (iMA(SMAfast,MODE_SMA,shift) - iMA(SMAslow,MODE_SMA,shift))/iMA(SMAslow,MODE_SMA,shift);
SetIndexValue(shift,MAValue);
if MAValue<0 Then
SetIndexValue2(shift,LoTrigger)
Else
SetIndexValue2(shift,HiTrigger);
loopbegin = loopbegin-1; // prevent to previous bars recounting
End

Too simple and 1 directional.
At the moment mq4 is too limited to give a decent answer. I would look into Tradestation for that.

sorry to waste your time
