我是说完全base在预测的基础上的trading,成功率不高。错了,能够及时掉头才是最重要的。当然说起来容易,做起来难,关键是怎么知道自己错了?呵呵。

所以我渐渐转为SELL OPTION / spread了. 即使方向看错,ENTRY LOUSY,还有点SAFETY MARGIN, because PREMIUM + TIME DECAY. 比如说SHORT SPY115CALL, 市场RISE,但没到115, you can still make $.
anyway, I am an option frog, I only bet as much as I am comfortable with stocks. 比如if only comfortable with shorting 500SPY, then only do 5 contracts. because gain is limited(the option premium), so exit plan is crucial. 比如我SELL NAKED PUT的时候,是做好准备万一ITM,要买下来STOCK的.
IB is great, $1/contract, good for me to scale in. TDAmeritrade charges $11 per trade! |
