Re: [EquisMetaStock Group] Re: If Then Else Neutral, MetaStock Email Archive

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.

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.
