Model's Performance Estimation

The next tab (System Performance) contains all necessary information for estimating the accuracy and profitability of your model. This is professional detailed trading statistics, with descriptions of all trades. Depending on the quality of your model, you can achieve great results. When you ask the program to predict stock movement, and get a set of signals, the performance tab is filled with statistical values and trades, and shows you your total net profit, percent profitable, profit factor, return on account, and many other parameters. Depending on these values, you can make a decision to recreate the model, or retrain it, or save it for further use.

There's the descriptions of System Performance Table fields:

Total net profit The grossprofit + grossloss.
Gross profit The total profit from all profitable trades.
Gross loss 

The total losses from all losing trades.

Total # of trades  The number of trades. 
Percent profitable  Percent of profitable trades is Winning Trades/ Total Trades * 100;
Number winning trades  The number of winning trades.
Number losing trades  The number of losing trades.
Largest winning trade  The amount largest winning trade.
Largest losing trade  The amount largest losing trade.
Average winning trade  The amount of the average winning trade.
Average losing trade  The amount of the average losing trade. 
Ratio avg win/avg loss  The Average Win to average loss is Average Win / Average Loss
Max consec. winners  The maximum number of consecutive winning trades.
Max consec. losers  The maximum number of consecutive losing trades.
Avg # bars in winners  The average number of bars in winning trades. 
Avg # bars in losers  The average number of bars in losing trades.
Max intraday drawdown  The maximum drawdown from a individual trade. Draw down is = Volume * Value of a Tick * (low price during the trade - high price the during trade) / Tick Size
Profit factor  Profit Factor
For long trades profitfactor = Long Gross Profit / Long Gross Loss
For Short Trades profitfactor = Short Gross Profit / Short Gross Loss
Max # contracts held  The largest volume traded
Account size required  Account Size Required to trade the account.
if margin = 100 then the Account Size Required equals the maximum drawdown, else Account Size Required = maximum drawdown / (margin / 100)
Return on account  Return on account
Short Account Return = 100 * Short Net Profit / Short Account Size Required
Long Account Return = 100 * Long Net Profit / Long Account Size Required
PRR  (((Net Win - pow(Net Win, .5)) / Net Trades) * Net Gross Profit / Net Win) /
(((Net Loss + pow(Net Loss, .5)) / Net Trades)* (-1) * Net Gross Loss /Net Loss)

if second half of above equation is zero then PRR is the first half. The PRR is used to determine how good a system is. 
PRR values from systems can be compared against each other to determine the best trading systems.
Open Position P/L Profit/Loss value of currently opened position, based on current stock price.
