Kospi 2000 future/option contracts are among the most liquid & volatile markets in the world . But limited by the low leverage (6.6:1) required by the exchange, one may find trading kospi futures contract is not efficient enough for your capital, although this market moves frequently and drastically during the sessions. I do not know whether it is due to this factor that kospi option contracts rises to be the most liquid one in the world, as option contract requires much less margin and kospi options is so liquid the spread is just one tick. I am in the time zone next to Korea, so I am looking into the kospi markets nowadays. I do not know if there are some Kospi traders on the ET bbs, if so , I have a question for you: what is the best option contract to daytrade in a way you trade a futures contract ( I mean, bet on directional movement), is that the one at-the-money ? And what is the contract to use, call option or put option ?
