Draw Price Levels

[tscript]

Draw Price Levels

I am looking to draw price levels for the daily charts when the price is the same for any opens, highs, lows, & closes. This is what I have in mind, or if something like this can be coded.

• For the daily charts. 1 month to 3 years.
• If the price is the same for any correlating opens, highs, lows, & closes, draw a price level connecting those candlesticks on the daily chart.
• Be able to adjust the color, style, width, ect of the price lines.
• Be able to adjust a price range surrounding the current price to display the price levels.

Example:​

• If the current price of a stock is $A and
• The price range is set to $B.
• Display the price levels ($C) around the current price ($A) +/- the price range ($B) on the daily chart.

Of course the current price ($A) will change depending on the stock symbol chart looking at, the price range ($B) will remain the same.​

• Be able to set only the top X# of price levels to be drawn with the most correlating opens, highs, lows, & closes within the price range ($B).

please edit your post,
remove 'price' and use open,high,low,close
what has to be the same? todays open to a past open? or todays close compared to any past open,high,low,close? i don't know what you want to compare.
get rid of letters to represent prices. its confusing. just use numbers.
if B is a range, then the levels would be at +B/2 and -B/2 from current ... close?
why use a range, if you want to find when an old price and current price are equal?

take a screen shot with windows snipping tool and edit it to show what you want.

here is something to experiment with. maybe its close to what you want.

pick how many bars back to compare. 100
compare 100 old close prices to the current close.
the first time that the difference of the 2 prices are < diff (0.03) then draw a line.
once a match is found, it stops looking for other matches

plot z1 = if old_price == 0 then na else old_price;


addlabel(1, "old price $" + round(old_price,2) , color.cyan);
addlabel(1, "price diff $" + diff , color.cyan);

addchartbubble(0, low*0.996,
