This is what I had in mind Kevin. If the two plots
have different colors then the original (second) plot will cover the exception
plot on all but the crossover bars. The first plot delays the relevant
MA on crossover bars but not others. Not sure if this is what you are looking
for.
HLd:=If(CLOSE>Ref(Mov(H,3,S),-1),
{then}1,
{else}If(CLOSE<Ref(Mov(L,3,S),-1),
{then}-1,
{else}0));
HLv:=ValueWhen(1,HLd<>0,HLd);
HiLo:=If(HLv=-1,
{then}Mov(H,3,S),
{else}Mov(L,3,S));
break:=Cross(hlv,0)-Cross(0,hlv);
If(break=1,Ref(Mov(H,3,S),-1),If(break=-1,Ref(Mov(L,3,S),-1),hilo));
HiLo;

Sorry, it I missed seeing the original plot from
MC's code as it was masked by third plot. Great minds think
alike?

Hi Kevin
After looking at MC's code it occurs to me that
a possible visual solution to your problem could be to have
two plots, one as per the original and one where the value from the
point of crossover is held for one bar longer? The delay for the second
plot would only be applied to specified bars, not to the entire plot. I
haven't attempted to code this thought but I'm confident that it wouldn't be
that difficult to do.
Regards
Roy

Re: If Then Else Neutral
Hello Preston,
Many thanks for your reply.
Unfortunately,
this formula still doesn't do the trick as it just shifts the original
plot back a bar. The principle is correct when using the Gann HiLo
Activator for intraday trading but for trading daily bars, the plot must
be offset by one bar (according to Gann).
On the bar on which the
trend direction changes, i.e. where the close is above/below the 3MA
high/low, the plots should overlap, i.e. there should be BOTH a Mov(H,3,S)
AND a Mov(L,3,S) plotted, not one or the other, which is the result of
HiLo:=If(HLv=-1,Mov(H,Lb,S),Mov(L,Lb,S)).
The reason
being is that when trading the Gann System, and a long trade is taken on,
say, a close above Mov(H,3,S), the initial stop is a break below
Mov(L,3,S). That is why we need the plots overlapping on that bar. The If
statement as it stands gives us an either/or.
Once again, I really
appreciate your input.
Regards,
Kevin

Kevin,
The formula was
originally written back in 1999 and posted on the
Guppy site back in
April of 2000. Strange that no one saw the problem
until now. Maybe
a result of the bear market.
The formula as posted works
correctly. It plots either a 3MA high or
a 3MA low overlaping on the
bar at which the close is greater/less
than " YESTERDAY'S " MA.
Notice the use of the ref statement in the
first
line...HLd:=If(CLOSE>Ref(Mov(H,3,S),-1) So we are indeed
looking for a close greater that yesterday's MA.
To make the
change you want simply change the formula to:
{Gann HiLo Kevin
Modified}
Lb:=Input("Look-Back
Periods?",2,80,3);
HLd:=If(CLOSE>Mov(H,Lb,S),
{then}1,
{else}If(CLOSE<Mov(L,Lb,S),
{then}-1,
{else}0));
HLv:=ValueWhen(1,HLd<>0,HLd);
HiLo:=If(HLv=-1,
{then}Mov(H,Lb,S),
{else}Mov(L,Lb,S));
HiLo;{end}
Now
you should get a resulting plot of either a 3MA high or 3MA
low on
the bar at which the close is greater/less than the "current"
MA.
