Once, silly brother was honest about buying at the bottom and placing orders in spot markets. I have recently started buying and selling options and dual currency wealth management. Some insights to share with everyone: 1. Dual currency wealth management charges high transaction fees based on option call and put. About 35% of the royalty, damn it! 2. Delivery method: Binance options are all delivered on a U basis; And for dual currency wealth management, if the put is successfully exercised, BTC will be delivered. That is to say, options cannot replace the role of spot buying. 3. Variables involved in option operations: price, time call、put、 Buy/sell. It is indeed much more complex than spot goods. Considering the understanding of delta and gamma, in fact, most retail investors are not suitable to play like this. 4. There are probably three uses, one is for bottom fishing, the other is for daily financial management, and there are also wave bands.. 5. Duan Yongping: The only reason to sell Put is that you already wanted to buy this stock at this price. Besides, never sell Put just to earn option premiums For true experts, "bottom fishing" and "financial management" achieve perfect quantum entanglement through the action of selling put. 6. If I don't understand BTC and I don't know when to buy at the bottom, I think it's a long-term volatile asset. So in this situation, selling put for a long time is a slightly positive operation, but in practice it will result in losses. 7. Taleb: There is no top master who hates and despises' selling Put 'the most. The person selling Put is the turkey before Thanksgiving who thought being fed every day was the norm until it was sent to the slaughterhouse. 8. Taking all factors into consideration, selling put cannot be considered as a long-term investment strategy. Only around the appropriate target and price can one perform actions similar to bottom fishing. The combination of bottom fishing and financial management is the strategy of not losing left and right. The logic of bottom fishing can be in terms of price range, value drop, and long-term perspective. Selling put to buy at the bottom also carries a risk, which is the risk of going short. 9. Correspondingly, selling a call is equivalent to selling assets and shipping. 10. In volatile market fluctuations, selling options adds an extra layer of "margin of error" compared to buying and selling spot stocks directly. The risk is the Gamma explosion caused by a unilateral breakthrough. 11. What to do when encountering a major drop? Direct spot trading, options are not direct enough, too cumbersome Although the above content may be boring, it is a skill that must be mastered in trading.
