ARW_new (MultiCharts)

[Tams 20]

This thread is about drawing an arrow on the chart. (MultiCharts enhanced EasyLanguage)

 

 

 

Arw_New

 

Displays an object, consisting of an up or a down arrow located at the specified bar and specified price value, on the chart that the study is based on; returns an object-specific ID number, required to modify the object.

 

Usage

 

Arw_New (BarDate, BarTime, PriceValue, Direction)

 

Parameters

 

BarDate - a numerical expression specifying the date of the bar at which the object is to be placed;

the date is indicated in the YYYMMdd format,

where YYY is the number of years since 1900,

MM is the month,

and dd is the day of the month

 

BarTime - a numerical expression specifying the time of the bar at which the object is to be placed;

the time is indicated in the 24-hour HHmm format, where 1300 = 1:00 PM

 

PriceValue - a numerical expression specifying the price value (vertical position,

corresponding to a value on the price scale of a chart), where the object is to be placed

 

Direction - a logical expression specifying the direction of the arrow;

True = Down and False = Up

 

Example

 

Place, on the chart that the study is based on, an up arrow at the top of a bar if the Open price has increased incrementally over the last three bars:

 

If Open>Open[1] And Open[1]>Open[2] Then

Value1 = Arw_New(Date, Time, High, False);

 

----------------------------------------------------------------------------

 

Arw_New_self

 

Displays the arrow on the SubChart.

Here's a demo.

 

The arrow is placed when the short term moving average crosses the long term moving average.

Tams, It's nice to extract such interesting possibilitie

 

May I ask a question ?

 

After that avg.st crossed above avg.lt how to compute x points above the X and draw an other arrow?

 

Pseudo Code

 

if avg.st crosses above avg.lt = OK

 

if price > (OK + 3 points) then

id.arw = ARW_new(date, time, OK + 3 points [1], false);

 

if price > (OK + 5 points) then

id.arw = ARW_new(date, time, OK + 5 points [1], false);

[Tams 20]

each ID can only be used once per bar.

if you want another arrow on the same bar, you have to define another ID.

 

e.g.

var:

id.arw2(-1);

 

id.arw2 = ARW_new(date, time, OK + 3 points [1], false);

let's take one step further:

 

...number converted to text... then added to the arrow.

Nonono sir

 

It's my fault = my explanations are always complicates :haha:

 

Is it Better with a graph ?

a picture is worth a thousand words... ;-)

 

 

the logic should be:

if avg.st crosses above avg.lt then OK = avg.lt;

 

 

 

for targets, it is better to use trendlines. (ie horizontal line)

This one looks logical but doesn't work

 

Please, Show me the way to the next (whisky bar) step

 

input:
st.length(	20	),
lt.length(	50	), 
arw.size(	18	);

var:
avg.st(	0	),
avg.lt(	0	),
id.arw(	-1	),

OK(		0	),
Sell.1(		0	),
id.arw2(	0	);

avg.st = averagefc(close, st.length);
avg.lt = averagefc(close, lt.length);

plot1( avg.st, "avg.st");
plot2( avg.lt, "avg.lt");

if avg.st crosses above avg.lt then 
	OK = avg.lt ;
if Sell.1 = (OK + 3 points) then
	id.arw2 = ARW_new(date, time, highest( high, 1 ), true );	
		   ARW_setsize( id.arw2 , arw.size   	);

[Tams 20]

you have to write out your thought process...

 

write them out:

-- one action at a time,

-- one action per sentence,

-- one sentence per line...

 

 

 

you can give this code a try...

 

I have drawn the trendlines for you,

you can decide on how/where to position the arrow.

p.s. because the 2nd arrow is not on the same bar as the 1st arrow,

you can use the same ID and do not have to create id.arw2.

This algorythm is really a master piece of logic :thumbs up: (at my modest level)

 

I should have not be able to do it but I understand 100 % of the progression

 

It reminds me the lighted maths school hours.

 

I'm so happy !!!
