why did my limit order not get filled 
a limit order may not get filled for a few reasons first your limit order will only trigger when market pricing meet your desired contract amount if a security is trading above your buy order or below your sell order it will likely not fill until there is price action on your security a limit order can only fill if a security has liquidity if the security does not have enough shares trading at the specific price you placed your order may not fill this is most common for larger orders placed on low volume securities due to volatility a stock on the day of its ipo may have difficulty filling due to rapid price fluctuation
