Replicate & Enhance ByBit trade calculator for Bitcoin Inverse Perpetual

I need a calculator for Bitcoin (BTC) trading to aid in strategizing BTC Inverse Perpetual trades by replicating the calculator shown here: [login to view URL] Ideally written in Ruby on Rails. Python also works. The key difference is all the calculations should be provided on one output table (their calculator resets for each of the four screens). Also noting most importantly that the last tab provides inputs on addition entry prices and quantities and will result in an average entry price, I need to be able to enter multiple inputs in the same way, those calculations are shown here: [login to view URL] Scope of Work: - Construction of a calculator for Bitcoin Inverse Perpetual trading, incorporating necessary calculations and formulas. - Integration of functions such as Profit/Loss, Target Price, Liquidation Price, and Entry Price from the Bybit Inverse BTCUSD calculator into a unified table output. - incorporating all the functions of their calculator shown here: [login to view URL] (look for the calculator button on the upper right side just below the trade button and immediately next to the margin multiplier) - see more information here: [login to view URL] - Inverse Example: use the example at the end of the article in the first link above. - Formula's and the examples are given in these pages: [login to view URL] [login to view URL] [login to view URL] Deliverables: - one cohesive and comprehensive calculator, ideally in a format that I can see all the code and formulas behind it. - User-friendly data entry fields, output table thoroughly tested for accuracy that aligns exactly with the calculations shown on ByBit's calculator - Detailed documentation explaining the usage, input fields, and output interpretation for both calculators. - All necessary iterations to get it to work as needed Ideal candidates for this project have experience with bitcoin trading platforms, financial calculations and good math and decent coding skills. The goal is creating a tool that works more effectively and more efficiently than Bybit's trade calculator while providing accurate calculations.
