A BiyaPay analyst has issued a warning about potential volatility in U.S. stock markets as the next Triple Witching Day approaches on December 19. This event, which sees the simultaneous expiration of index futures, options, and stock options, is expected to bring sharp market swings due to a record notional value of expiring contracts. Volatility indicators are pointing to increased intraday fluctuations and trading volumes. Traders are advised to adjust their positions in advance, avoid impulsive trades, and implement stop-loss and partial orders to mitigate risks. Additionally, day traders in both crypto and equity markets should reassess their margin and order prices to minimize slippage and the risk of liquidation.
