Capture peak or valleys when price crosses 200-SMA?

[Mohammad]

@halcyonguy,

Could I make a request: Capture peak or valleys when a price crosses above or below a 200-SMA? I have seen several similar codes from you, such as box for an oscillator when ob/os and for fibs in addition to the new one you added to check if price is near a moving average; so, I think you are the right person. But, not being a developer, the indicators seem hard to modify for my needs.

Specifically:

1. After the prices crosses above and closes above, plot two Median Prices (MP) on the chart as Cyan Squares or Yellow Squares on the identified bars:
A: First Median Price: the valley (lowest) between this cross above and the prior cross below.
B: Second Median Price: the bar when it Crossed and closed Above the 200-SMA.

2. For example, Apple crossed above the 200SMA on Feb 2nd, 2023. Prior to it, it cross below from above on Aug 30th, 2022.
A: First Lowest MP: Of candle when AAPL crossed above on a Daily chart was: HL2 on Jan 5, 2023.
B: 2nd Median Price of the candle when it Crossed Above (and closed above 200SMA): HL2 of Feb 2nd, 2023

3. Condition: Use the first cross (Above or Below) of the 4 bars near each other (input variable) and ignore the other within in the 4 bars; for cases of multiple up and downs. (or if you recommend different number of bars to ignore the noise).

4. Detect if the median price crossed above or below the 200SMA

5. Colors: If Crossed Above from below, plot Cyan squares, for the two Median Price of the Bars (MA Cross Above and the Lowest MP). And, Yellow Squares for the opposite scenario: the two Median Prices, when the prices crosses Below from Above, of the median price of the highest bar/candle.

6. Time-frame: entire chart (I usually use a 2-3 year, Daily; but can reduce to 1-year if there are system performance constraint. but plots on the entire chart, rather than last ones are highly desirable)

Any help would be greatly appreciated!

I hope this is a complete description of what I am trying to plot. Please let me know if I can clarify anything.

hello,
make a request of a specific person? sure. although by doing do, may limit the answers you get. there are many good programmers here who may have a good answer.

---------

if i don't understand something, i ask a lot of questions. please don't take it wrong. i am just trying to get you to describe the problem in a different way.

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

i'm sorry, i am confused by your words and have no idea what you are asking for.
i think you want to find valleys..??
between signal crossings?

there are several things that need clarifying.

in your step 1, it's like you are starting out in the middle of a story. mentioning things that haven't been described, so it doesn't make sense.

from your #'s
1. you don't say what is crossed. you mentioned sma200 earlier , but didn't mention in step 1.
what defines a median price (mp)?
when did a mp happen?
draw a square on the bar with a crossing? or on the bar with a mp?
should start out by describing what they are and when they happened.

1a ?? not sure. mp is a valley?
1b ?? not sure. mp is a bar at a crossing?
i have no idea what you are describing.

2b. is mp HL2?
that should have been mentioned in the first sentence.

i suggest you rewrite the rules, and if you make up terms, like median price, then describe them at the beginning.

I have used Valley in my studies so I think I know you mean, but it's still best to describe what it means to you.


you have an image with numbers 1, 2, 3.. but i don't know what they represent.
could have listed descriptions right above the picture.
1. is this..
2. is this
3. is this..


you used a shortcutcut link instead of a bbcode link for the image.
doing so places that logo for imgur.

Thank you @halcyonguy . I am trying out the code above you created and let you know by either answering the above questions or if I have any questions.

Also, no doubt we have many capable and generous leaders in addition to yourself. Forever indebted to you and everyone who openly shares great and open ideas.

maybe this can be a starting point for what you want ?

Thanks again. I have been looking at it. It's very good and very close. Also, leveraging the zig zag study makes sense. Please allow me to provide better details and attach an image or two as well.
