Gann HiLo Activator

[Apprentice]

On Metatrader platform I use Gann HiLo Activator indicator,
very useful indicator.

Looking for developers who can encod Gann HiLo Activator indicator for MarketScope

Gann HiLo Activator is basically a simple moving average of the previous 3 periods' highs or lows plotted based in relation to the HiLo Activator.

Gann High Low - Metastock Indicator Formula

{name: GANN-HiLo}

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));
HiLo;

Hello Apprentice,

I forwarded your request to the developers. They said they will try to get this indicator done for you this week. One of us will post it as soon as its done.

Cheers.

If I understand the Metaquotes code correctly, the indicator displays simple moving average for the last N (i.e. including the current) periods of either High or Low values.
In case current close value is greater than average high of previous N periods, the indicator shows average low value. In case the current close is less than average low of the previous N periods, the indicator shows average high value. In case the close is neither greater previous than average high nor less than previous average low, the indicator chooses High or Low to show as it was for the previous period.

The indicator which works in that logic is attached. Could you please check whether it's the indicator you need.

Thanks guys for the effort, the indicator is perfect,
I recommend using 10 periods, as the default value.

You can use it to generate buy and sell signals and set stop loss orders.
I use it along with the ADX, QQE indicators, QQE can be replaced with RSI or TSI.

You can use it for all time frames.

is there a signal available for this indicator ?

[Apprentice]

Such signal was not yet written.
Added to the Development cue.
