Yes, you generally have to pay for shorter timeframe charts and real time pricing. Tradingview and Stockcharts are the best but other technical traders here might want to chirp in to talk about others?
Tradingview can be used on US stocks using BATS live pricing but most will use paid accounts which really aren't expensive considering one can lose a lot more money on a trade than what you pay per month.
RSI is certainly a good way. For example, on a downtrending stock and sector like ACB and MJ, traders look for oversold on the 1 hour chart RSI less than 20 and will generally sell when it recovers to RSI about 50. If the stock is uptrending, they will wait for overbought at RSI above 80 on the 1 hour.
Best way to learn? chartguys youtube videos. They work mostly on candlesticks, higher highs, higher lows, lower lows, lower highs etc eto determine trend. There's hundreds of ways to do TA, I combine multiple techniques and also look at fundamentals. But fundamentals can be fudged. Especially in Canada with the lose IFRS vs US GAAP which is tighter.
