How markets orders work on sim101

[coolmoss]

I have a strategy which submits a market order to buy, once price is X ticks above the prior bar. The strategy is COBC=false, so my understanding is that once the High[0] + X Ticks is touched, a market order is submitted to Sim101.

Is NT filling this simulated order based on some sort of algorithm? Where the fills actually occur are usually several ticks worse or better than one would expect. On the sim account, I would have though the market order fills would be either exactly at the submitted price or perhaps 1 tick worse to account for a minimal bid/ask spread.

Thanks for clarifying.

Hello,

The NinjaTrader simulation engine is designed to operate as realistically as possible.


From our Help Guide:

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?simulation.htm

NinjaTrader provides a state of the art internal simulation engine that can be used to test trading ideas and hone your skills. The simulation engine is not a simple algorithm that fills your order once the market trades at your order price. The engine uses a scientific approach to determine fill probability by including a number of variables including: ask/bid volume, trade volume, time (to simulate order queue position), and random time delays for switching between order states.

You can decrease this type of slippage by enforcing immediate fills in the Sim101 account. Please take the following steps:

• From the Control Center, click Tools > Options to open the options menu.
• In the Options menu, navigate to the Simulator tab.
• In the simulator tab of the options menu, check the box labeled 'Enforce Immediate Fills'.
• Click OK to exit the options menu for the change to be applied.

Please let me know if there is anything else I can do for you.
