Fair Value Gaps

Would be really great if someone could create a bullish and bearish FVG indicator with option to leave or close when mitigated , it’s all I use on trading view along with standard ICT stuff …

Fair Value Gaps are Essential when trading off the algorithms macros day to day . I won’t get into why ,Bc if you know you know etc…

You could take the TV contributors LM or LuxAlgo free pinescripts and adapt ? Idk I do not code .

Thank You for your consideration
Best
