Try etoro for starters. I think that for Stocks is fine but for cryptos the spreads are a little to much. For cryptos try Binance or other crypto Exchange. In trading view you can also use Hitbtc or OANDA. Click on trading panel on the bottom of trading view page. THIS IS NOT ANY RECOMMENDATION. ONLY THE ONES THAT I'M WILLING TO TRY. I'M ONLY ON ETORO FOR NOW AND SOME AIRDROP CRYPTO ON HitBTC. Search others recommendations.
