Gravestone Doji

Recommended Posts

Hi

Does anyone out there know the Tradestation Easy Language code for a Gravestone Doji? Or where I could get it? Am looking for an alert to sound when one appears on a chart.

I know Tradestation has a show me indicator for Doji's. but was just wanting the Gravestone.

 

Thanks

Hi Tams

 

Thanks for the speedy reply.

 

The Gravestone is a bar where the open, low and close are all at the same price. Ideally I would like it to find that bar when the high of the gravestone is higher than a previous x number of bars. Meaning the gravestone is at the top of a move.

 

When the gravestone occurs, I would like either a dot or preferably a down arrow printed just above the candle. Also I would like the option to have an audio alert attached.

 

Is all this possible?

 

Thanks

Hi Tams

 

Thanks for the speedy reply.

 

The Gravestone is a bar where the open, low and close are all at the same price.

 

 

is it possible?

 

sure it is possible...

 

if you can imagine it, you can do it.

 

if you can articulate your logic on paper, it can be coded.

 

if you can write out your thoughts one action, one line at a time,

even a non-programmer can program in EasyLanguage.

 

here's a little help to get you started:

 

 

var:

gravestone(false);

 

gravestone = (open = low) and (open = close);

Thanks. I will give it a go here.

 

var:

gravestone(false);

 

gravestone = (open = low) and (open = close);

 

Also

 

Gravestone = If high > Highest (High, Length )[1] then

 

Plot ( down arrow)

 

Alert;

 

End;

 

Am I along the right lines? Copied highest high bit from breakout of X bar high indicator.

 

Go easy on me. Have never even looked at this code stuff before.

write out your logic in English first...

 

one thought at a time,

one action at a time,

one action per thought,

one thought per line,

one line per sentence...

 

 

eg.

if XXX > YYY, then

do ZZZ...

etc.,

 

 

Go easy on me. Have never even looked at this code stuff before.

 

 

no worries, EasyLanguage is nothing more than structured English (the computer way).

sit back, relax, take this as a step by step free EasyLanguage lesson.

 

 

 

var:

gravestone(false);

 

this line creates a variable called gravestone.

 

 

Variables

 

Variables are a programming tool that allow you to store values and refer to those values when needed.

 

Each variable has a unique name that can be referenced in an analysis technique when needed.

 

Variables can be:

numeric values, or

true/false comparisons, or

text strings.

 

 

Variables allow you to organize and annotate your code with descriptive names that describe the nature of the calculation or purpose of the data. Variables hold their value from bar to bar until changed.

 

There are several benefits to storing values in variables: they can reduce typographical errors, complex state-

ments can be referred to by a simple name, readability and understanding are improved, and they are processing

and memory efficient.

 

Variables names, like inputs, are unique to the study they are declared in. You can use the same name over

again in any other study, but you cannot reuse the same name within the same study, for example declaring

a variable with the same name as an input. Also, remember to avoid naming variables with the same name as

an EL reserved word or function.

 

User-named variables must be declared before they can be used. The Variables reserved word is used to

declare variables, and it has four forms: Variables, Variable, Vars, Var. Each is functionally

equivalent and each must be followed by a colon ( : ), then a list of variable names separated by commas.

 

Each declared variable must be given an initial value. Variables are generally initialized to 0, but can be

initialized to any useful value. This initialized value determines the data type of the variable (numeric, true/

false, or text string).

 

Usage Example:

 

Variables:

LastHigh(0), { creates a numeric variable }

NewHigh(false),{ creates a true/false variable }

HighAlert(""); { creates a text variable }

Ok. Trying to run before I can crawl!!

 

Here goes again. In English.

 

gravestone = (open = low) and (open = close);

and

high > than previous 5 bar highs

If both conditions met.

Then plot a down arrow

Down arrow to plot above gravestone

Alert

When down arrow plotted

 

Any better??

gravestone = (open = low) and (open = close);

 

 

in this code, I have assigned a "value" to gravestone.

 

i.e.

 

gravestone MEANS (open = low) and (open = close);

 

 

 

in another words,

 

when I say gravestone, I really mean:

 

(open = low) and (open = close);

 

 

 

when someone say he can see a gravestone, he really means:

 

he can see a (open = low) and (open = close);

 

 

 

 

but wait a minute... didn't I jsut created the variable gravestone and assigned it a (false) value?

 

Yes, I initialized the value to false.

 

The computer will evaluate the condition at every bar and see if the condition is met...

 

if the condition is met, then gravestone will become "TRUE".

 

 

 

so far so good?

yes, you have got it...

 

Let me edit it a bit.

We are still at the pseudo-code stage.

Here you can see the English writing is starting to take on the structure of a computer code.

 

 

// state the condition

gravestone = (open = low) and (open = close);

 

// the evaluation:

if gravestone is true

and

high > than previous 5 bar highs

 

// the operation:

then

do this:

-- plot a down arrow

 

 

 

 

Piece of cake !

Thanks Tams. your help is much appreciated.

 

I cut and pasted your code into a new easy language show me file. It did not like the word gravestone. i stuck a VAR: in front of it but that seemed to cause more problems. I also deleted the words "down arrow". Was that right?

 

PS. I did leave school back in the seventies, hence my ignorance re computer programming.:)

arh... I shouldn't have colored it blue.

sorry for the confusion.

I will go back and change it to another color.

Tams.

Found a post you did re arrows. Have inserted the text you used. How does it look??

 

 

// state the condition

gravestone = (open = low) and (open = close);

 

// the evaluation:

if gravestone is true

and

high > than previous 5 bar highs

 

// the operation:

then

do this:

-- plot Arw.point.Down

Arw. size (18);

arrow is more advanced stuff... let's tackle one challenge at a time.

 

 

 

homework for the weekend:

 

look up the following keywords:

plot

setplotcolor

 

 

 

Enjoy!

 

 

p.s. arrow is only available for MultiCharts.

YES !!! YES !!! YES !!!

 

this is great!

 

This is 100% EasyLanguage logic !

 

 

All we have to do is go to the EasyLanguage dictionary/manual

and find out the syntax of the keywords.

It now verifys upto 5. Does not like it. Would I need to put in some sort of Inputs field re the no of bars back??

On the contrary, I did look up the file "Gap Up Bar" in the show me section. Hence I moved a couple of things, but it did not tell me too much. It's probably not the file you meant. Currently looking at Gap & Reverse Up.

 

Really don't know what i'm looking at or for:confused:

 

Is it to do with BarNum as a variable or am I going down a blind alley. I do really appreciate your help, but on a scale of 1 to 10, 10 being Eureka. how close am I to 10? Begining to think I might be under a dam gravestone before I get this right!!:frustrated:

 

Cheers

    • Date: 29th March 2024. GBPUSD Analysis: The Pound Trades Higher But For How Long? The global Stocks Markets are closed due to Easter Friday (Good Friday). The NASDAQ continued to follow the sideways trend while other indices again rose. The SNP500 reaches an all-time high, but the NASDAQ remains under pressure from Tesla, Meta and Apple. The Euro continues to trade lower against all major currencies including the US Dollar, Euro and Japanese Yen. The British Pound is the best performing currency during this morning’s Asian session. However, investors are largely fixing their attention on this afternoon’s Core PCE Price Index. GBPUSD – The Pound Trades Higher but For How Long? The GBPUSD is slightly higher than the day’s open and is primary due to the Pound’s strong performance. At the moment, the British Pound is increasing in value against all major currencies. However, the US Dollar Index is also trading 0.10% higher and for this reason there is a slight conflict here. If investors wish to avoid this conflict, the EURUSD is a better option. This is because, the Euro depreciating against the whole currency market avoiding the “tug-of-war” scenario. The GBPUSD is trading slightly lower than the 2-month’s average price and is trading at 49.10 on the RSI. For this reason, the price of the exchange is at a “neutral” level and is signalling neither a buy nor a sell. The day’s price action and future signals are possibly likely to be triggered by this afternoon’s Core PCE Price Index. Analysts expect the Core PCE Price Index to read 0.3% which is slightly lower than the previous month but will result in the annual figure remaining at 2.85%. The PCE rate is different to the inflation rate and the Fed aims for a rate between 1.5% to 2.00%. Therefore, even if the annual rate remains at 2.85%, as analysts expect, it would be too high for the Fed. If the rate increases, even if only slightly, the US Dollar can again renew bullish momentum and the stock market can come under pressure. This includes the SNP500. Investors are focused on the publication of data on the UK’s gross domestic product (GDP) for the last quarter of 2023: the quarterly figures decreased by 0.3%, and 0.2% over the past 12-months. This confirms the state of a shallow recession and the need for stimulation. The data, combined with a cooling labor market and a steady decline in inflation, increase the likelihood that the Bank of England will soon begin interest rate cuts. In the latest meeting the Bank of England representatives did not see any members vote for a hike. USA500 – The SNP500 Rises to New Highs, But Cannot Hold Onto Gains! The price of the SNP500 rises to an all-time high, before correcting 0.33% and ending the day slightly lower than the open price. Nonetheless, the index performs better than the NASDAQ which came under pressure from Tesla, Meta and Apple which hold a higher weight compared to the SNP500. For the SNP500, these 3 stocks hold a weight of 9.25%, whereas the 3 stocks make up 14.63% of the NASDAQ. The SNP500 is also supported by ExxonMobil’s gains due to higher energy prices. The market will remain closed on Friday due to Easter. However, the market will reopen on Monday for the US and investors can expect high volatility. Investors will also need to take into consideration how the PCE Price Index and the changed value of the US Dollar is likely to affect the stock market next week.
