You can open this page from the Control Panel → Acceptance Criteria
The Acceptance Criteria are widely used in FSB Pro (Generator, Optimizer etc.). Those are minimal requirements to the strategy.
Each time the program backtests a strategy, it also computes if it passes the Acceptance Criteria. You can easily see in the Strategy Statistics if the strategy fulfills the acceptance criteria. If it did not pass the Acceptance Criteria – the row of the table will be orange, so it is easy to notice.
Maximum ambiguous bars (default: checked; 10) – the strategy has to have equal or less than 10 ambiguous bars
Minimum profit per day (default: checked; 1) – it should profit at least one USD or EUR per day. If you disable this option, the Generator and Optimizer will show strategies with negative profit.
Maximum equity drawdown [currency] – the account equity should not go below the given value of account’s currency
Maximum equity drawdown [points]  the account equity should not go below the given value in points
Maximum equity drawdown [%]  the account equity should not go below the given percent value
Minimum count of trades (default: checked; 100) – how many trades should be at least in the backtest. This is important for the Generator and Optimizer so the backtest statistical data is “realistic”. If there are too few trades, the parameters below might have goodlooking 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.
Maximum count of trades – you can set a number here, to make sure the strategy is not overoptimized. You can also avoid losing money on the spread by trading less.
Minimum win/loss ratio – The win/loss ratio is ( (number of profitable trades) / (number of profitable trades + number of losing trades) ). Its value might vary between zero and one. We advise that, if you are using this requirement, to keep the “Minimum number of trades” and “Minimum profit per day” requirements enabled too.
Minimum Sharpe ratio – You can read more about this parameter here: http://www.investopedia.com/terms/s/sharperatio.asp
Minimum system quality number – “SQN measures the relationship between the mean (expectancy) and the standard deviation of the Rmultiple distribution generated by a trading system. It also makes an adjustment for the number of trades involved. Dr. Tharp has determined that the better the SQN, the easier it is to use various position sizing strategies to meet one's objectives.” See: http://www.vantharp.com/tharpconcepts/sqn.asp
Maximum consecutive losses – how many consecutive losing trades can the strategy have Maximum stagnation – the maximum amount of consecutive days where the strategy is not making a profit. The stagnation is marked with a vertical orangebackground zone in the Portfolio
Filter nonlinear balance pattern – on the picture below. The Reference line is an ideal line, which represents how the strategy’s balance should move up in ideal conditions. This is of course impossible. The line deviates from the Reference line. This parameter (the nonlinear balance parameter) represents how far away the real balance moves from the Reference line. For example, if the parameter has a value of 20%, each of the points of the balance line, should not deviate more than 20% (up or down) from the value of the reference line for that bar. If the strategy’s balance line moves further than 20% of the reference line, the strategy does not fulfill this criteria.
You can create the following criterion: A line with a given direction with minimal fluctuation of the balance line. In other words – to test if the strategy makes regular profits, whereas its balance does not fluctuate much.
Those two actions will assure the strategy will make profits throughout the whole period of the backtest without fluctuating too much.
