Feature Request - Fill all orders for backtests

I understand that all orders are not always filled but for the purposes of back testing it would be helpful.One may have a winning strategy but would never know it because none of the orders are filled during the backtest..

Just a thought.

Example from logs

Try doing this:

def initialize(context):  
    set_slippage(slippage.FixedSlippage(spread=0.0))  

that did it, thanks!

That does not work for me! i'm still getting this regardless.
