-Simulations run in the time period active at the moment of clicking the RESTART SIMULATION button. Only one time period may be active at any point in time: if you run a simulation in a different time period than a previous simulation, the previous one stops—however, the previous simulation data is conserved and may be accessed again by going back to the corresponding time period.
+Testing sessions run in the time period specified in this parameter.
-## Simulation Processes
+Available options at the sub-hour level are:
-Once you run a simulation, it keeps running for as long as the node.js processes are running at the console. When the simulation reaches the present time, it remains active, calculating dynamically as new data is retrieved from the exchange.

-If you click RESTART SIMULATION, processes are stopped and restarted. This results in past simulation data for the same *time period* being deleted and new data being written as the calculations advance.
+Available options at larger time periods are:
-The simulation process is associated to the Definitions structure present at the moment of running the simulation. Changes you make in your Definitions afterwards are only taken into account when you restart the simulation.
-
-All of these considerations apply for Live Trading as well.

+The layer manager allows you to determine which visualization layers will be available at the Layers Panel to plot the results of testing sessions over the charts.
-The Trading Simulation layer displays a backtest + forward test (paper trading) of whatever strategies you have created in the system. At sign up, you are provided with an initial set of strategies so that you can be up and running as quickly as possible.
