估计版内有很多人搞高频交易, 楼主确实说出了高频交易的一个很重要的要素: capital deployment strategy A good capital deployment strategy for HFT is never use up the margin to do "all in". If all buying power was used up in any moment, the 震荡损耗 will be eating up the trading profits if it happened to lose money in the trades when you were all in. Some people even use a "fixed dollar" trading strategy 说到底这其实是一个risk-reward balance issue. 有高频交易经验的可以继续深入讨论,呵呵

做option 有巨幅上下波动时这个道理仍然有效,当你all in 赔掉30%后, 你需要下次能 挣40% 才能办回来,呵呵

计算涨跌,都是股市入门须知,这个就不用提了。 因为hft整套我不懂,所以我无权说话。针对range市场,我也不会这么做。 option操作这种,无法单个止损,做法丰富多样。 没有人傻到all in option作为常态。 总之,交流之后,依然是看不上话唠妹的帖子,没有贬低的意思,只是个人观点。
