-The **acceptance criteria** are widely used in EA Studio (in the [[eas-guide:generator|Generator]], [[eas-guide:reactor|Reactor]], [[eas-guide:validator|Validator]], [[eas-guide:optimizer|Optimizer]]). The acceptance criteria serve as a filter when a new strategy is generated or enters EA Studio. If the strategy passes it will be pushed to the respective [[eas-guide:collection|collection]]. For example if acceptance criteria are enabled in the Optimizer it will not display strategies that do not pass the acceptance criteria.+The **acceptance criteria** are widely used in EA Studio (in the [[eas-guide:generator|Generator]], [[eas-guide:reactor|Reactor]], [[eas-guide:validator|Validator]], [[eas-guide:optimizer|Optimizer]]).

-Acceptance criteria work based on the strategy backtest. The strategy backtest results can be seen in **Strategy > OOS Monitor** tab or **Strategy > Report** tab. OOS Monitor is better since you can see the distinct zones of in sample and out of sample testing plus the complete backtest of the strategy.+The acceptance criteria work based on the strategy backtest. The strategy backtest results can be seen in the **Strategy > OOS Monitor** tab or in the **Strategy > Report** tab. We recommend using the OOS Monitor since there you can see the three distinct zones and their backtest stats.

-If you find a strategy with the Generator that you like you can set the acceptance criteria so the generator will find similar strategies. Just go to the **Strategy > OOS Monitor** and see the results of the backtest. Then enter them in acceptance criteria settings. For example if you liked  a strategy that has a drawdawn of 8% in the acceptance criteria settings enter a number that is a little biter more loose - 10%  for Maximum drawdawn etc. From now on the generator will only give you strategies that fit these criteria.+If you find a strategy with the Generator that you like you can set the acceptance criteria so the generator will find similar strategies.

-EA Studio backtesting engine is very fast because it operates with bar data. Very rarely however this leads to ambiguities in trading decisions. For example if there are protections like Stop Loss or Take Profit it might be important if the price went to bar's high or low price first. For such bars the backtest engine cannot what happened first so it marks the bar as "ambiguous". This happens rarely but this criterion allows you to require a high percentage of the bars to be unambiguous to consider the strategy good enough.+The EA Studio backtesting engine is very fast because it operates with bar data.

-Defaults to 100. At least that much trades should happen in the backtest. This is important for the Generator and Optimizer in order for the backtest result to be trustworthy. If there are too few trades, the parameters below might have good-looking values, but in the same time harm your profits. For example if you have a win/loss ratio of 1.0, it is great, but if the trade count is only one, this strategy not one you can rely on.+Defaults to 100. This means the strategy should make at least 100 much trades in the backtest.

 Shows how stable the profits are over time. Imagine we have a strategy with **minimum months of profit** equal to 60%. This means that if the strategy backtest was for 10 months of trading we can see that the strategy was profitable for 6 months and in the other 4 months it didn't make any profits. Shows how stable the profits are over time.
