need info on algos to purchase/sell in low volume stocks/options

[Forex Trader]

I have a profitable blackbox for low volume options (yes enough to almost always make up for the spread).. but I need some help on best ways to purchase/liquidate options w/ 50-150 vol a day.

any pointers, books, algos, keywords to look in for in research for building a buying/selling side of a blackbox?

thanks!
