FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package position-sizing-data
position-sizing-data
Reference data and arithmetic for position sizing across forex, stocks and crypto futures.
This repository exists because the numbers behind "how many units should I trade" are usually scattered across broker pages, forum posts and screenshots. Here they are in plain CSV and Markdown, with the formula written out, so anyone can check the arithmetic instead of trusting it.
An interactive implementation of the same calculation lives at https://positionsizetool.com/.
An archival copy of this dataset is deposited at Zenodo: doi:10.5281/zenodo.22840538. Use that DOI to cite the data in anything that outlives the repository.
The same tables and formulas are published as installable packages, so the arithmetic can be checked from a REPL instead of a spreadsheet: position-sizing-data on PyPI (source in pypi/), position-sizing-data on npm (source in npm/), and the Go module in this repository, which embeds the CSV files so go get github.com/tk25719/position-sizing-data needs nothing else. PHP users can composer require tk25719/position-sizing-data; that package ships in composer.json and src/.
The four data files are also mirrored on data platforms, each with the same provenance note attached: the canonical landing page is positionsizetool.com/reference-data.html, and the mirrors are Kaggle and Hugging Face.
Contents
| File | What is in it |
|---|---|
data/contract-specifications.csv |
Default contract size, pip size and unit step per instrument, for 131 symbols across forex, metals, energies, indices and crypto. |
data/pip-value-by-lot-size.csv |
Pip value per standard, mini, micro and nano lot, on a USD-denominated account, plus the cost of a 20-pip move and of a 1-pip spread. |
data/losing-streak-equity.csv |
Equity remaining after 1 to 20 consecutive losses at 0.5%, 1% and 2% risk per trade. |
data/drawdown-recovery.csv |
Gain required on the reduced balance to return to the original balance, for drawdowns from 5% to 90%. |
checklists/pre-trade-risk-checklist.md |
What to confirm before an order goes in. |
docs/position-sizing-formulas.md |
The formulas, why each term sits where it does, and a worked example. |
The formula in one line
The tradable size is that number rounded down to the broker's unit step. Rounding up increases risk without saying so.
The full derivation, including why the spread is added to the stop distance while the commission is subtracted from the budget, is in docs/position-sizing-formulas.md.
Where the numbers come from
- Instrument rows are the built-in defaults of the calculator linked above. They are typical retail contract specifications, not exchange-published official values, and several are editable by design. Verify the contract size and unit step of your own instrument against your broker before placing an order.
- Everything else in
data/is computed, not copied. Each table has its generating formula stated at the top of this table's entry below:losing-streak-equity.csv:remaining = (1 - risk%)^ndrawdown-recovery.csv:gain_required = 1 / (1 - drawdown) - 1pip-value-by-lot-size.csv:pip_value = units x pip_size, converted to USD at the stated rate
