Ocil is right .
the error caused due to the version problem.
if anytime in future u face this problem then plz remove one of the zero frm last 5 parameters in tht line and ur code will be ok.

in ami version higher than 5.50 it uses 5 last parameters on the other hand in ami version les than 5.50 it uses 4 or less last parameters.

for further ref plz chk the afl reference.

anyways the code looks in future. plz check with Code check and profile.

u might not get the same result u r getting now in the running market.
it will repaint the sig. generatred.

so be carefull.....

It is working fine....can anybody interpret hw to use it.

Thanks

That is a million dollar question, ashraf

You will find 1000s of amazing AFLs but very few will explain what is plotted.

In a way it is correct too (I suppose) because that alone will bring out your own subjectivity into it and thus have possibility that the same chart
can tell two different things to two different people.

Easiest way to understand any afl is to break it apart and then reconstruct it and make notes of each part that gets added ...

First understand the Trendlines drawn are called Tom Demark Supply/Demand Lines
Second understand the Horizontal lines are called the Entry/Stoploss/Target Lines

How it work:
========

Supply Line is Orange, Demand Line is Blue.
Trigger: Buy candle is Yellow, Sell Candle is Magenta

Buy Condition:
When Price cross up Supply Line, Buy candle trigger, Entry/SL/TGT lines ploted upward.

Sell Condition:
When Price cross down Demand Line, Sell candle trigger, Entry/SL/TGT lines ploted downward.


How to find out?
There is a [Bar Replay] button, use it.
Play it with your historical data, watch it develop

That simple

Thanx you Kelvinhand,

Gr8 explanation...u r gr8 asset to this forum. Hates off..





One request..

Help needed to plot exploration??



Conditions -

A) buy - When Price cross up Supply Line, Buy candle trigger

B) Sell - When Price cross down Demand Line, Sell candle trigger

C) i have habbit to explore in daily chart..
my need is - i want which script Yellow and magenta fresh candle formation coming..
(Exploration of Yellow or Magenta candle in exploration)
Thanx you in advance.

You n Johnny are gr8 asset to this forum.

Waiting for ur help.
