* Initial concept for creating price tracking pairs * Completes coverage, even with a slow test * I dont know what point to hook this stuff up * Bit of a broken way of handling tracking pairs * Correctly calculates USD rates against all currencies * Removes dependency on GCT config * Failed currency statistics redesign * initial Update chart to use highcharts * Minor changes to stats * Creats funding stats to handle the stat calculations. Needs more work * tracks USD snapshots and BREAKS THINGS FURTHER * Fixed! * Adds ratio calculations and such, but its WRONG. do it at totals level dummy * End of day basic lint * Remaining lints * USD totals statistics * Minor panic fixes * Printing of funding stats, but its bad * Properly calculates overall benchmark, moves funding stat output * Adds some template charge, removes duplicate fields * New charts! * Darkcharts. funding protection when disabled * Now works with usd tracking/funding disabled! * Attempting to only show working stats based on settings. * Spruces up the goose/reporting * Completes report HTML rendering * lint and test fixes * funding statistics testing * slightly more test coverage * Test coverage * Initial documentation * Fixes tests * Database testing and rendering improvements and breakages * report and cmd rendering, linting. fix comma output. rm gct cfg * PR mode 🎉 Path field, config builder support,testing,linting,docs * minor calculation improvement * Secret lint that did not show up locally * Disable USD tracking for example configs * ShazNitNoScope * Forgotten errors * "" * literally Logarithmically logically renders the date 👀 * Fixes typos, fixes parallel test, fixes chart gui and exporting

Statistics package overview
The statistics package is used for storing all relevant data over the course of a GoCryptoTrader Backtesting run. All types of events are tracked by exchange, asset and currency pair. When multiple currencies are included in your strategy, the statistics package will be able to calculate which exchange asset currency pair has performed the best, along with the biggest drop downs in the market.
It can calculate the following:
- Calmar ratio
- Information ratio
- Sharpe ratio
- Sortino ratio
- CAGR
- Drawdowns, both the biggest and longest
- Whether the strategy outperformed the market
- If the strategy made a profit
Ratios
| Ratio | Description | A good range |
|---|---|---|
| Calmar ratio | It is a function of the fund's average compounded annual rate of return versus its maximum drawdown. The higher the Calmar ratio, the better it performed on a risk-adjusted basis during the given time frame, which is mostly commonly set at 36 months | 3.0 to 5.0 |
| Information ratio | It is a measurement of portfolio returns beyond the returns of a benchmark, usually an index, compared to the volatility of those returns. The ratio is often used as a measure of a portfolio manager's level of skill and ability to generate excess returns relative to a benchmark | 0.40-0.60. Any positive number means that it has beaten the benchmark |
| Sharpe ratio | The Sharpe Ratio is a financial metric often used by investors when assessing the performance of investment management products and professionals. It consists of taking the excess return of the portfolio, relative to the risk-free rate, and dividing it by the standard deviation of the portfolio's excess returns | Any Sharpe ratio greater than 1.0 is good. Higher than 2.0 is very good. 3.0 or higher is excellent. Under 1.0 is sub-optimal |
| Sortino ratio | The Sortino ratio measures the risk-adjusted return of an investment asset, portfolio, or strategy. It is a modification of the Sharpe ratio but penalizes only those returns falling below a user-specified target or required rate of return, while the Sharpe ratio penalizes both upside and downside volatility equally | The higher the better, but > 2 is considered good |
| Compound annual growth rate | Compound annual growth rate is the rate of return that would be required for an investment to grow from its beginning balance to its ending balance, assuming the profits were reinvested at the end of each year of the investment’s lifespan | Any positive number |
Arithmetic or versus geometric?
Both! We calculate ratios where an average is required using both types. The reasoning for using either is debated by finance and mathematicians. This is a good breakdown of both, but here is an extra simple table
| Average type | A reason to use it |
|---|---|
| Arithmetic | The arithmetic mean is the average of a sum of numbers, which reflects the central tendency of the position of the numbers |
| Geometric | The geometric mean differs from the arithmetic average, or arithmetic mean, in how it is calculated because it takes into account the compounding that occurs from period to period. Because of this, investors usually consider the geometric mean a more accurate measure of returns than the arithmetic mean |
USD total tracking
If the strategy config setting DisableUSDTracking is false, then the GoCryptoTrader Backtester will automatically retrieve USD data that matches your backtesting currencies, eg pair BTC/LTC will track BTC/USD and LTC/USD as well. This allows for tracking overall strategic performance against one currency. This can allow for much easier performance calculations and comparisons
