小白问个问题

$迅雷(XNET)$ 我看到9.21号的期权交易价格，如果我看多，买5.00的看涨期权要交10.40费用相当于15.4，可买10.00看涨的话要交7.20相当于17.2，价格越高总费用越贵。我想请问那是不是应该买最低价格的呢？而且越便宜的岂不是越保险？假设最终价格是8.00，那5.00的还能有点儿剩余价值，10.00的就是废纸了？不是很懂，请大家指教

不要给我谈梦想
按道理是买总价低的更容易盈利，但你付出的权利金更多啊，如果方向赌反了，股价下跌，你的损失就是10.4而不是7.2。但如果买7.2的，虽然便宜，但总价高，股价。要超过17.2才可以盈利
- 不要给我谈梦想回复风云再起2018:
  之前卖过一次趣店期权put，权利金1300,执行价12.5结果到到期跌到12.3被行权了，手上多了200股股票，显示亏损2200。。。还以为可以赚1300结果亏2200
- 风云再起2018回复不要给我谈梦想:
  你可以通过卖出看空期权来做多，但是这样杠杆率就比较低，因为开义务仓保证金要求高
- ppp回复不要给我谈梦想:
  估计互金会先买的put option...
- 不要给我谈梦想回复ppp:
  迅雷涨那波本来是赚的，结果中间出来个金融协会乌龙，第二天全亏了，估计是空军自救，故意搞新闻
- 不要给我谈梦想回复ppp:
  我经常被割，习惯了，没办法，资金少，不然买正股加put慢慢涨
三倍杠杆玩期权

三倍杠杆玩期权
5跟10的call，5块比10块贵，你相同的钱买到的数量是不同的，越价外的杠杆率越高，如果达成了收入就越高，当然风险也越大
- 不要给我谈梦想回复ppp:
  风险不是更小，是更大，因为付出的权利金更多，但是方向买对的话，更容易赚钱。买反了亏更多
- ppp:
  好像有点儿琢磨过来了，杠杆不同，我有7000美金的话，5块的只能买7手，10块的可以买10手。10的杠杆高，所以收益大风险大
- ppp回复三倍杠杆玩期权:
  麻烦大神看一下我又发了的图，是每一手的。那我5块买1手是1060，买10块一手的话只花740。难道这就是为什么10块比5块合算？可最终结账的时候算下来5块便宜很多啊～风险也比10块小很多。。。
- 三倍杠杆玩期权回复ppp:
  价格乘以100才是你要付的钱
- ppp:
  可是价格加手续费算下来，5块的比10块的便宜啊，5块的总共是15.4，10块的是17.2。。。请问杠杆是什么？如果股价到了20，不是一个挣4.6，一个挣2.8？
