I’m not sure if a single base URL is a good idea, but in general it could be that there is a set of providers to choose from - like alpha, yahoo or regional ones depending on market. Then there could be an option for something entirely custom. Of course, a first version could be much simpler than that
Also, I understand you mean that it’s quickly accessible from the table - so you don’t have to open the asset - just click something. The symbol itself is a too small target to make it work on mobile, but there could be a dedicated button nearby for that.
At this moment, you can always paste the link in the Asset’s Notes - notes are then visible when you open the asset’s page and links are clickable.
I like this idea, give us a few variables to craft our own URLs. https://www.tradingview.com/chart/?symbol={EXCHANGE}%3A{TICKER}
where EXCHANGE = NASDAQ and TICKER = GOOGL to get me to https://www.tradingview.com/chart/?symbol=NASDAQ%3AGOOGL
