Tools / Calculator

Expectancy and SQN. What an average trade of yours is worth.

Paste your trade results, one per line. You get the average result per trade in R, a quality score called SQN, and the rough edges: losing streaks and drawdown. The box starts with 30 made-up trades. Replace them with yours.

Method described by Dr. Van K. Tharp (Van Tharp). Daksh Analytics is not linked to them.

Used to turn rupees into R. Default ₹5,000.

Losses with a minus sign. Commas like 1,200 are fine. Lines that are not numbers are ignored and listed.

SQN counts at most 100 trades: with more than 100 results it is worked out as if there were exactly 100, so scores stay comparable between traders. Averages and drawdown use every trade. Van Tharp's bands: below 1.6 poor; 1.6 to 1.9 below average; 2.0 to 2.4 average; 2.5 to 2.9 good; 3.0 to 5.0 excellent; 5.1 to 6.9 superb; 7.0 and above is the top of the scale.

Results are hypothetical and for illustration only. Not a guarantee. Not investment advice.

How it works. In plain words.

First every result is turned into R: how many times your planned risk the trade made or lost. A result of 2R means twice the amount you risked, and -1R is a normal full loss.

Expectancy is the average of those results. A positive number means trades like these made money on average. It combines your win rate with the size of wins against losses, which win rate alone cannot do.

SQN divides that average by how much your results jump around, then scales it by the number of trades (up to 100). Two traders with the same average can score very differently if one is steadier.

The longest losing streak and the biggest fall in running total (drawdown, in R) show what living through these results felt like. Under 30 trades the page warns you: a small sample can look good or bad by luck. To see how a win rate and payoff could turn into account risk, try the risk of ruin calculator.

For the curious

R = result in rupees / 1R in rupees (or the number as typed, if already in R)

expectancy = mean of R

standard deviation = sample standard deviation of R (divide by N - 1)

SQN = square root of min(N, 100) x mean / standard deviation

drawdown in R = largest fall of the running total of R from its previous high
