Does anyone that uses TradingView execute from the platform? If not, Is it slow execution or what?

Thanks

You mean actual chart trading from the platform? It works and they integrate with a ton of brokers. If you're in the US, (which it looks like you are), there are way better platforms for chart trading for which you can buy outright a lifetime license like NT8 or Multicharts. Apparently, Tradestation is very good and people also love ToS.

I was supposed to make a live trade with IKBR through my Tradingview a week ago but it wouldn't let me one click buy so I was immediately turned off. Multicharts handles that way better.
