Riskarb, here is quote from original post:
<QUOTE>I bought september put ( eur / usd ) strike 1.2300,
and it is now is in-the-money.</QUOTE>
What it tells me is that those puts were in the money only after some time and not at the time of their purchase. If those options are priced with arbitrage it does not make any sense to wait some time until they may or may not become in the money. One can buy in the money put options immidiately & make money from arbitrage. So arbitrage was not initial intention at the time of buying put options. And that is relevant for me in terms of overall trading strategy which is not arbitrage.
