就是说，我当天买了，我看到涨了，就卖掉的，差价就是赚了，向反就陪了，这是什么样的呀？？我想搞这样的
T交易也就是T+0交易
你想搞这样的,目前只能搞权证.股票还是T+1
Option. call and put
Call option . You have the right to buy the underlying security at a preset price (strike price). You have the right means that You don't have to sell or buy.
Say, you pay me 2 dollars each share for 1000 shares IBM $45, I will garantee that no matter how much the price is going to be 1 week later, you will have the right to buy 1000 shares of IBM from me at $45 . Then 1 week later, IBM is trading at $60, you will exercise your call option and I will have to sell you 1000 shares of IBM at $45 dollars. so your profit will be 60-45-2=13, in the case if you sell 1000 shares IBM back to the market.
this is a example of Option trading. We call these things as financial derivatives.
