A small day trade successfully executed

This afternoon I executed a small day trade buying Hang Seng Index put warrants (17863) at HK$0.058 and selling them back at HK$0.060. As always, I only use very small amounts of money for these speculations. If I lost the lot, it would not affect my retirement plans (only my ego). It also means that the profits will be correspondingly minuscule. The net profit on the trade was about 1.6% and will be enough to buy a decent bottle of wine.
