      If you decide to take a position in a particular stock, don't takeyour eyes off it for a second. Triple-witching days are very unusual, andvolatility is high. This strategy is risky, but the profit potential ishigh. When in this type of trade, set a low risk tolerance, and exit thetrade immediately if it starts to go against you. You may wish to considerentering trailing limit and stop limit orders 3/8 behind your trade (notethat stop orders are only available for listed securities). By continuouslyupdating your limit or stop limit order, you can lock in your profits andlimit your losses. The downside to the use of limits and stop limits isthat you might get "picked off" or "shaken out" of what otherwise wouldhave been a profitable trade. Depending upon how far from the inside quoteyou set your limits or stop limits, you can reduce the risk of gettingpicked off or shaken out of a trade. However, the farther out that you putthe trailing stops or limit orders, the higher will be your risk of largerlosses.
