Besides learning everything you can from guys like sle, bone, maverick74, destreiro, puffygums, and some of the other legends of ET, you can read books. Financial mathematics books are good. Any knowledge you can get about microstructure, market making, and the players in the market (banks, brokers, HFT, commercials) will be better than anything else you could learn. Industry knowledge is the thing every trader wants and needs. But, that's hard to come by. Go to this site and check out this stuff http://sp-finance.e-monsite.com/

Here's a quote from a guy who worked at the Board of Trade.

[I don't trade vol and make no claims about the accuracy of the statements on that site]Also, put–call parity says that you can enter into a straddle by buying a call and a put, or two calls and sell a stock or two puts and buy the stock. A straddle is very sensitive to volatility. Indeed, the Gamma and Vega of a straddle are positive and two times higher than the Gamma and Vega of a call. The holder of a straddle is obviously long volatility.

Industry knowledge is solid gold. Those gurus on youtube are full of shit.The market you see and trade now is not the same market I traded 20 Years ago. The changes did not occur overnight, and there is not one reason, but a multitude of reasons, that precipitated the change. Government regulations, the electronic trading revolution, the economy, Fed monetary policy, and negative headline events, all contributed to the degradation of the market we enjoyed in the past.
While the advent of decimalization in 2001 is probably the biggest culprit in the gradual demise of the market, the nascent decline began in 1997-1998 with the change in Order Handling Rules and Reg ATS, which opened the door to pervasive market fragmentation (followed by Sarbanes-Oxley in 2002 and Reg NMS in 2005 and you have a history of legislation that has worked to destroy what were once, very liquid and trade-able markets.)
Liquidity was allowed to be spread across multiple markets, exchanges, and trading venues. Unfortunately however, the true purpose and usage of tools like dark pools as mechanisms to effect large block trades for large mutual and pension funds, has been perverted to a means to feed internalization and proprietary HFTs. Today, the NYSE executes approximately 26 percent of the volume in its listed stocks. The remaining volume is split among more than 10 public exchanges, more than 30 dark pools, and more than 200 internalizing broker-dealers. 30 percent of volume in U.S.-listed equities is executed in venues that do not display their liquidity or make it generally available to the public.
Decimalization made High Frequency (automated) Trading possible — a business tailor-made for trading large capital companies at the expense of small caps and IPOs. Add to this the rise of Index and Exchange Traded Funds and all the action was soon in large cap stocks. Market makers were no longer supporting small caps by being a willing buyer to every seller...
