Here is a SAR cross trading system for this Above40MA indicator :
In many MeanIndicators the smoothing factor 35 is very good for the 
N100 market and I use it
without hesitation as the first option.
SAR parameters may also vary for better results.
Get an idea from

// The Above40MA and its SAR 
Above40MA=DEMA(100*Foreign("~>ma40","v")/101,35);
H=Above40MA;L=Above40MA;
cc=SAR(1,0.2 );
d1=Optimize("d1",25,20,25,5);
d2=70;
Buy=Cross(Above40MA,Cc) AND Above40MA<d1;
Sell=Cross(Cc,Above40MA) AND Above40MA>d2;
Short=Sell;
Cover=Buy; 

At d1=20 we have 6 trades since the summer of 2000, at d1=25 we have 
7 trades.
The whole market gives >+300% total net profit for both parameters.

83% to 85% of the N100 database is profitable with
buy/sell/short/cover at +1Open, stops disabled.
Ideal for ^NDX, QQQ with 7trades/7winners/0losers ,total net profit 
at +385% amd maxSysDD -32%
The "guarantee" of the system : applied to the [contrarian] ^VIX 
[with a 50% stop loss to avoid total ruin] 
gives a sweet -95%, another strong indication that we speak for an 
interesting system.

think it is a decent market condition indicator.  I am not yet 
capable of doning any coding, so if someone decides to write 
Amibroker code that will allow  this so it can be displayed in 
Amibroker, I would appreciate your posting it here in this group.  I 
use the free yahoo EOD data.  Ron D

> Has T2108 nailed it again? You'll recall that I've been using this 
chart -- which is nothing more than the percentage of NYSE stocks 
over their 40-day moving average -- as somewhat of a buy/sell 
oscillator. When the percentage gets above 70%, that marks a top. 
When it gets down into the mid-20% range, it's a buy. Down much 
lower, and it's a bottom.

openings, the S&P has not closed higher than it did on April 2 and is 
now down 1.7% since that day!
