The Backstory

During our final year research, my girlfriend and I dove deep into futures trading. We developed a strategy that demanded quick reactions to market movements. But when theory met practice, we hit a wall.

The platforms weren't built for speed. Every trade required calculating position sizes, checking liquidation levels, accounting for fees—then navigating through multiple form inputs just to place an order. In fast-moving markets where seconds matter, this friction was costing us.

So I built Inuxi. A tool that collapses all that complexity into a single keystroke.

Inuxi Main Interface

The main interface overlay that calculates risk, leverage, and fees instantly.


The Problem

Binance Futures doesn't provide built-in tools for calculating proper position sizes based on risk. Traders are left to manually:

  • Calculate margin requirements
  • Account for trading fees
  • Check liquidation levels
  • Verify risk-to-reward ratios

This process is slow, error-prone, and nearly impossible to execute quickly when the market is moving against you.


The Solution

Inuxi reads your TradingView Risk/Reward drawings and instantly calculates everything you need:

  • Margin & Leverage — Automatically determined from your risk tolerance
  • Liquidation Price — So you never get caught off guard
  • Breakeven Point — Accounting for all fees
  • Profit/Loss Estimates — At your take-profit levels

Then it lets you execute the trade directly on Binance with a single keystroke.


Features

Auto-scraping — Pulls entry, stop-loss, and take-profit levels directly from TradingView charts.

Smart Calculations — Position size, leverage, R:R ratio, and estimated fees—all computed instantly.

Liquidation Safety Check — Prevents order execution if your stop-loss puts you at liquidation risk.

One-Click Execution — Place orders directly on Binance Futures without touching the order form.
