How to track Gulden Price on MacBook Pro Touch Bar!

Many people want to track the price of Gulden all day long. Thanks to the MacBook Pro Touch Bar it’s possible in a whole new way!

Article by Harm Jan van Kammen.

Here’s a step-by-step hands-on guide on how to accomplish this. 

Before anything is even remotely possible you’ll need to install the following applications:

After you’ve installed BetterTouchTool: run it, go to the TouchBar tab and click the + Widget button. Next, in the Select Widget drop down, select Run Apple Script and Show Value and then click Advanced configuration.

After that you can name your widget, mine is called Gulden. Then you can use the following script to get the data from Nocks Trade to fill it with the correct data. Just copy and paste it into the text field and you’ll be good to go!

set mJson to do shell script "curl -s 'https://guldendex.com/api/eurprice.php'"
set AppleScript's text item delimiters to {","}
set keyValueList to (every text item in mJson) as list
set AppleScript's text item delimiters to ""
set theKeyValuePair to item 15 of keyValueList
set AppleScript's text item delimiters to {": "}
set theKeyValueBufferList to (every text item in theKeyValuePair) as list
set AppleScript's text item delimiters to ""
set usdPrice to item 2 of theKeyValueBufferList
set theKeyValuePair to item 12 of keyValueList
set AppleScript's text item delimiters to {": "}
set theKeyValueBufferList to (every text item in theKeyValuePair) as list
set AppleScript's text item delimiters to ""
set change to item 2 of theKeyValueBufferList
set usdPrice to RemoveFromString("\"", usdPrice)
set usdPrice to RoundImperialNumberToTwoDecimals(usdPrice)
set change to RemoveFromString("\"", change)
set arrow to " ▲"
if change < 0 then
set arrow to " ▼"
end if
set unformatedValue to "€ " & usdPrice & " " & arrow & " " & change & "%"
return RemoveFromString("\"", unformatedValue)
-- remove character or string from given string
on RemoveFromString(CharOrString, txt)
set AppleScript's text item delimiters to CharOrString
set temp to txt's text items
set AppleScript's text item delimiters to ""
return temp as text
end RemoveFromString
on RoundImperialNumberToTwoDecimals(txt)
set AppleScript's text item delimiters to "."
set decimals to text item 2 of txt
if (count decimals) < 2 then
set decimals to decimals & "0"
end if
set decimals to (text 1 thru 4 of decimals)
set theNumber to text item 1 of txt & "." & decimals
set AppleScript's text item delimiters to ""
return theNumber
end RoundImperialNumberToTwoDecimals

This code will retrieve the last price at Nocks Trade and return it to the widget. I won’t take any credit for this piece of script, I found it at this post and as you can read the original came from Charlie Lee. I just altered it to show the price in Euro and traded the source of the data to my own source that gets the data from the Nocks API. I also altered it to show 4 decimals like Nocks does.

Now you can style your widget. First up, the logo. I used the following one: https://dev.gulden.com/images/branding/gwhite32x32.png. You can just drag it into BetterTouchTool in the icon slot and after that the alternative icon slot. For the Touchbar Button Collor and the Alternate Color i used #2AB0FD since it’s the original Gulden color as stated on their website https://dev.gulden.com/contribute/.

If you styled your widget to your likings please set the Execute this script every x seconds to above 60 seconds to make sure my server won’t overheat! Click save and you’re done!

Let me know if you like it!
