Distinguish-between-green-red-candle-in-Blocks

Extracted your offtopic post (from a thread now locked for reply) here. There may be several ways to distinguish a black candle from a red candle. One of the most obvious techniques is to use the 1-period ROC indicator. It's above 0 when a candle is green and vice versa.

But it might be natural to have such rule straight in the "Candlestick Pattern" list (green/red candle).

As per definition of a green bar ...

Method 3 - Use Candle Codes: Requires the [Candesticks Genetic Evolver Extension](https://www.wealth-lab.com/extension/detail/Candlesticks)

Once installed, see User Guide > Extensions > Candlesticks > Candle Codes

The advantage here is that you can give the candle context too. For example, a "green" candle could still be green, but close lower than the previous day.

Here's a code for:
- green candle (BC:W), and,
- has a long body length (BL:L), and,
- is a higher close than the previous bar (CONSEC:1UP1 or P-:1C>C)

CODE:
Long Green Higher Close=BC:W.BL:L.CONSEC:1UP1
or
Long Green Higher Close=BC:W.BL:L.P-:1C>C

Note: Control what's considered "Long" in Preferences > Candlesticks.

Thanks to all.

I will test all methods.

@Cone

I can't find "Current candle is a Long Green Higher Close." And Candle Codes too.

You have to add it manually. Re-read the second line in my post. Follow the instructions in the Help Guide. You can create any pattern you can think of using the gene codes there.

Hi Cone,

I am going in WL to extension, open Candlestick Genetic Evolver. Then I can see Pattern and CandleGene Code (Genetic Evolver). But I can't find an instruction how to create a new candle pattern.

Am I in the wrong users guide?

User Guide > Extensions > Candlesticks > Candle Codes

Well, gosh, it's not step by step, but starting with the second sentence in the first paragraph...
...You can create your own Candle Patterns using the gene codes by adding records to the CandlePatterns.txt file in the User Data folder. To generate the file just run the Candlestick Evolver and save one of the Genetically Evolved Patterns. Close Wealth-Lab before editing CandlePatterns.txt.

The whole page is about how to create patterns. But you don't even have to read it for this one because I gave you the pattern above.

Here's the step-by-step:
1. Install the Candlesticks Evolver extension
2. Run it and save one of the genetically-evolved Patterns.
3. Click File > Open Wealth-Lab User Data folder.
4. Close WealthLab
5. Open CandlePatterns.txt
6. Add your patterns to it and save it.

Just add these 3 patterns to CandlePatterns.txt.

CODE:
Green Body=BC:W
Green Higher Close=BC:W.P-:1C>C
Green-Long Higher Close=BC:W.BL:L.P-:1C>C

Note that the last code for the "long" body depends on Preferences > Candlesticks and requires some history to determine what is "long" for the BarHistory.

OK. Got it.

Thanks.

Hello,
Does anyone know how to discover a candle with shaved head and shaved bottom?

And not exaclty shaved bottom/head namely:
Bull Candle: Open Price nearly low Price; Close Price nearly High Price.
Bear Candle: Open Price nearly High Price; Close Price nearly Low Price.

Regards,

Right here:
User Guide > Extensions > Candlesticks > Candle Codes

Did you try it?

@Cone

Do you mean these Codes in the Evolver ?


Because, I can't see the path Extension > Candlesticks > Candle Codes

Like Cone said, it's in the User Guide to read first.

I don't know what you mean with your User Guide.

I can see the Quick Ref., Wealth-Lab Help F1 and Wealth-Lab Website Support.

I have check all three things. I can't see any Candle Codes.

The whole thread is an example of how to create your own Candle pattern. The key to the Candle Genes is in the User Guide, which in Build 22 will have the step-by-step that I created for you in Post #8.

I am sorry, there is no user guide after installion candlesticks evolver. I've send the picture twice.

Please, added in build 22.

Sorry, it will not be added in B22B. Look for next build of the Candlesticks extension when Robert is ready with his changes.

Okay.

I picked out from the pattern library (Evolver) from different pattern.
I think I've put together the desired pattern.

Bullish GreenBodyWithoutShadows=BL:W.V:M,P-:1C>C.RL:L.SL:+S

Re: user guide after installion candlesticks evolver

What are you guys talking about? Everything that is required is in the User Guide since at least Build 20. I only added the steps that you can already see above in Post #8.

We added Candlesticks specific guidance in the WL8 User Guide? I would have expected that to go into the Candlesticks Extension documentation.

I'm posting this maybe 4 times now?

User Guide > Extensions > Candlesticks > Candle Codes

Glitch knows this (because he programmed it), but when you install an extension, its help becomes part of the WL8 User Guide.

Edit - I see the misunderstanding. When I said "Build 20" I was referring to the cycle of extension releases that were available with Build 20.

Hi,
yes that's right.

And I also said that I can't find the topic with Candle Codes in the user guide.

Okay, that explains it - we neglected to release Build 4 of the Candlesticks extension when it was ready 5 or 6 weeks ago! We'll get that done this week.

Build 4 with the documentation is ready now!
