Option Heatmap and OI Strikes For ThinkOrSwim

using mountain king date code here is what i came up with for optionseries
AddLabel(1, "." + getsymbol() + Concat((ExpY1),"") + Concat((ExpY2),"") + Concat((ExpM1),"") + Concat((ExpM2),"") + Concat((ExpD1),"") + Concat((ExpD2),""), CreateColor(135,135,135));
Using the old code:
AddLabel(yes,(concat(".", concat(getSymbolPart(), concat(concat(EXPYear - 2000, if ExpMonth2 <= 9 then concat("0", ExpMonth2) else concat("", ExpMonth2)), if ExpDOM <= 9 then concat("0", ExpDOM) else concat("", ExpDOM))))));

I keep getting an error when trying to define as variable however, it says expected double

my date code parsed the yyyymmdd format to try and account for errors in option call ticker symbol into yymmdd with zeroes in the first position of the two digit date code -- nowhere near perfect but check and make sure the Exp variables are all properly calculated. I think halcyon pointed out that it wasn't necessary to do what I did. in the old code they tried to insert a zero if expdom <=9 -- I tried to turn the date into a decimal and "shear off" the digits to create the date. I really wish TD would just make expiry variables for us so this isn't necessary.

is the error with the old code or mk?

use the manual version I shared via link earlier. can you guys please change it so it grabs open interests instead of volume.
 
and increase the strikes ranges to maybe 60 instead of 19

Okay Everyone the code is good for the most part, only thing that is an issue is plotting the lines with center strike, i trouble shoot it and the issue is when i enter a number for the centerstrike variable the plot shows up, however when i use a formula such as floor((close/10)*10) or rounddown((close/10)*10), the plot will not show up but the volume figures do in the label.

Code:

great, looking forward to it, the dude on twitter changed his handle to private btw lol.
 
great, looking forward to it, the dude on twitter changed his handle to private btw lol.
I updated it, had some errors , also there is still the issue of getting the plots to come up, if no one comes up with a solution, we will have to sert centerStrike as an input and enter it manually
 
make sure not to mix my vars and the old vars
They’re not , your vars are ones I modify for monthly options using a different script , so there’s no confusion on that end. The issue is the plot, I still can’t wrap my mind on how those lines are able to plot like that , gonna have to do deep diving during a week I have free, because I think somewhere in there would explain why you can’t use a variable defined as a function for center strike , the option volume works fine it’s the plot that’s the issue, dates are good, although expdom will need to be modified back to 14 once options expire on next month on the 14th

got it to plot -- needed this code to see some lines

added easy input for date fix, auto feature back, fixed the price ranges, reorganized a bit and noted changes. deleted all old mk code as it wasn't being used. Positive!

Code still needs work but coming along nicely
