my trades today
1) at 9:30-9:35 market order short 118p, 119p, while they still worth something,
but didn't cover 121c (@0.42-0.45), b/c I didn't think today SPY could reach 121.
2) after 11:50 push up, short small position of 120p.
now short 121c was in serious trouble, 0.8x-0.7x.
3) covered all 121c @0.72 during bar 38-40.
because SPY haven't touched ema for ~3hours, I couldn't take it any more. ema is rising, I was afraid even if SPY touch ema later, it would be at about the same price level.
later, bar 46-48 1st ema touch, 121c@0.68-0.69. 尾盘没有最后的PUSH UP, 121c@0.67 看来我又猜错了.
偶卖OPTION捡PENNY, 通常是NAKED SHORT, 如果大错,会有某个STRIKE的赔得一塌糊涂, 要靠几个其它的STRIKE的去补救. 今天121C的损失,准备由119P弥补. (当然119P还没EXPIRE WORTHLESS YET, 如果再跌破120, 偶要被两面抽了). |
