Hello, I notice I receive the following error when I attempt to submit MarketOnCloseOrder's outside of 16 minutes prior to market close in my backtests:

"Backtest Handled Error: MarketOnClose orders must be placed with at least a 16 minute buffer before market close."

However, both NASDAQ and NYSE currently allow entering MOC orders at 3:55 pm and 3:50 pm respectively.

The 15 minutes prior to market close is obviously volatile and can signficantly impact strategy buy/sell triggers. 

Is there any way to override this behavior? 

This is specially important to me in "Go Live" behavior - for strategic purposes I'd like my strategy to make its decision at the last possible minute.
