ARW_new (MultiCharts)

Recommended Posts

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.

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);

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);

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 :confused:

 

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   	);

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.

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 !!! :)

    • Back in the early 2000s, Netflix mailed DVDs to subscribers.   It wasn’t sexy—but it was smart. No late fees. No driving to Blockbuster.   People subscribed because they were lazy. Investors bought the stock because they realized everyone else is lazy too.   Those who saw the future in that red envelope? They could’ve caught a 10,000%+ move.   Another story…   Back in the mid-2000s, Amazon launched Prime.   It wasn’t flashy—but it was fast.   Free two-day shipping. No minimums. No hassle.   People subscribed because they were impatient. Investors bought the stock because they realized everyone hates waiting.   Those who saw the future in that speedy little yellow button? They could’ve caught another 10,000%+ move.   Finally…   Back in 2011, Bitcoin was trading under $10.   It wasn’t regulated—but it worked.   No bank. No middleman. Just wallet to wallet.   People used it to send money. Investors bought it because they saw the potential.   Those who saw something glimmering in that strange orange coin? They could’ve caught a 100,000%+ move.   The people who made those calls weren’t fortune tellers. They just noticed something simple before others did.   A better way. A quiet shift. A small edge. An asymmetric bet.   The red envelope fixed late fees. The yellow button fixed waiting. The orange coin gave billions a choice.   Of course, these types of gains are rare. And they happen only once in a blue moon. That’s exactly why it’s important to notice when the conditions start to look familiar.   Not after the move. Not once it's on CNBC. But in the quiet build-up— before the surface breaks.   Enter the Blue Button Please read more here: https://altucherconfidential.com/posts/netflix-amazon-bitcoin-blue  Profits from free accurate cryptos signals: https://www.predictmag.com/ 
    • What These Attacks Look Like There are several ways you could get hacked. And the threats compound by the day.   Here’s a quick rundown:   Phishing: Fake emails from your “bank.” Click the link, give your password—game over.   Ransomware: Malware that locks your files and demands crypto. Pay up, or it’s gone.   DDoS: Overwhelm a website with traffic until it crashes. Like 10,000 bots blocking the door. Often used by nations.   Man-in-the-Middle: Hackers intercept your messages on public WiFi and read or change them.   Social Engineering: Hackers pose as IT or drop infected USB drives labeled “Payroll.”   You don’t need to be “important” to be a target.   You just need to be online.   What You Can Do (Without Buying a Bunker) You don’t have to be tech-savvy.   You just need to stop being low-hanging fruit.   Here’s how:   Use a YubiKey (physical passkey device) or Authenticator app – Ditch text message 2FA. SIM swaps are real. Hackers often have people on the inside at telecom companies.   Use a password manager (with Yubikey) – One unique password per account. Stop using your dog’s name.   Update your devices – Those annoying updates patch real security holes. Use them.   Back up your files – If ransomware hits, you don’t want your important documents held hostage.   Avoid public WiFi for sensitive stuff – Or use a VPN.   Think before you click – Emails that feel “urgent” are often fake. Go to the websites manually for confirmation.   Consider Starlink in case the internet goes down – I think it’s time for me to make the leap. Don’t Panic. Prepare. (Then Invest.)   I spent an hour in that basement bar reading about cyberattacks—and watching real-world systems fall apart like dominos.   The internet going down used to be an inconvenience. Now, it’s a warning.   Cyberwar isn’t coming. It’s here.   And the next time your internet goes out, it might not just be your router.   Don’t panic. Prepare.   And maybe keep a backup plan in your back pocket. Like a local basement bar with good bourbon—and working WiFi.   As usual, we’re on the lookout for more opportunities in cybersecurity. Stay tuned.   Author: Chris Campbell (AltucherConfidential) Profits from free accurate cryptos signals: https://www.predictmag.com/
