OOS Monitor Testing
OOS (Out of Sample)
During a strategy backtest, it is highly advisable to pick a specific time period from the data feed and keep it for testing at a later stage. The EA Studio provides you with this exact advantageous feature.
When you generate, test, and optimize a strategy over a certain historical data, we call this data IS (In Sample). The other term we use for it is Training data.
The OOS (Out of Sample) data or Trading data is a part of the historical data that you reserve.
It has a significant role when you estimate the success of a strategy because you test it over data that is not part of its initial optimization.
Since the OOS data hasn't impacted the creation of the strategy, it serves as a forecast tool. In other words, it facilitates the traders to see their strategy's performance on new data.
The program shows the OOS results in light green color.
There is a drop-down menu from which you can choose what percentage of the data to use for OOS Monitor testing.
