It seems there are many Bitcointalk members who use TradingView. So I think the problem is the tradingview system detected that you are using fake debit/credit card or you are using prepaid cards(Visa/Mastercard) or maybe they detected that you made multiple accounts.
And actually the weird thing is they only offering 14 days trial, not 30 days. How did you know that they have 30 days free pro trial?
It might differ from region to region. When I create a new account, I see ads for a 30-day trial. It's always been that way as far as I know. Years ago, I knew multiple people who would game their free trials every 30 days. It looks like they're trying to put a stop to that.
Well i never made any other accounts besides those 2, and my VISA is not a fake one

it's linked to my only bank account and i never had any problem with it ever.
And i made the 2nd account
after the first one got cancelled, thats why i'm pissed... i really dont like those companies who say they offer "free" trial or anything, while they force you to pay afterward, it's such a scammy marketing way to treat customers..
Do you have any other site like this to share by the way ? Similar to trading view ? i would actually rather pay a subscription to another company if i have to
Coinigy has very similar charting software and functionality. If you're an altcoin trader, it gives access to more coins and exchanges than Tradingview.
It sucks that you're facing these issues. It's been years since I did the free trial so I don't have any experience to offer. I do like Tradingview a lot. If you PM "admin" in the chat window, he may be able to help. He's always been able to get my issues fixed, though I'm mostly referring to technical stuff, not billing stuff.
