Tomorrow we'll take a look at the Ponzo forecast for SPY vs. QQQ volatility for the next 4 months.
But first, a little reminder that our favorite topic....risk....can be controlled to a large extent through careful application of order types, especially stops.
I personally have not entered a market order in 15 years...always defaulting to a limit order to either buy or sell. In after hours trading you can only enter limit orders on most platforms.
Regarding stops I generally prefer a stop limit order to an outright stop, especially for over night orders in order to avoid prop shop driven volatility at market opens.
Review the various order types below: (please note>>>the Trailing Stops link is not active.)
