TNR chart, page-411

I'd start with looking at basics of charting; learn the basics of candlesticks and the most common bullish and bearish pattern combinations as well as what individual candles mean in different places of a trend.

MACD is a good place to start, that will give a very basic (until you get a more comprehensive understanding) of where a stock is in a particular point; is it at the start or top of its run or continuing etc.

Timeframes are very important; daily and weekly for most investors/ position traders and then there's the intra day; hourly/30min/10min etc. for the traders and picking a precise entry point.

Elliot Waves are great but it's one specific method within Charting so start with basics and then branch out; also most just draw a bunch of lines and then say "hey here's 5 price movements it's an Elliot wave" when that's not always the case; same for things like flags; symmetrical triangles etc. and the worst culprit is the cup and handle which everyone says is there but those take months to form not a couple of weeks or days.

Wykoff theory is also a good place to look but go with basics and first work out what you're looking to achieve so you know what timeframes you need to focus on.

hope that helps a bit
