    Job Description: If you are familiar with Tradingview then you will know that we can apply script stategies to our chart. Problem is sometimes these indicators are private, meaning you can still add them to your chart but cannot see the source code of that indicator (Pinescript) written by the author. You can use Chrome Debugger tool to debug the Javascript and get the Pinescript of public scripts. However, with my limited skill in Javascript I could not do the same for the private ones but I'm pretty sure it is still possible using the same method.
