Stop Calculating Math on Raw Ticks.
Power Your Bots with Sub-100ms Telemetry.
Why spend weeks writing rolling EMAs, volume-weighted deviation bands, and market regime classifiers that crash your servers? KustomCode computes high-precision algorithmic indicators and active signal feeds in real time, serving them over ultra-fast REST and WebSockets for just $9.99/month.
Blazing REST responses and sub-100ms WebSocket streams.
EMA 9/20, session VWAP bands, and ATR regimes pre-computed.
Deterministic setups with win rates and risk-to-reward ratios.
No enterprise minimums. Billed in USD or ZAR via PayFast.
Built for Traders, Devs & Quants
Stop reinventing basic financial mathematics. Focus on your trading strategy while we handle the data pipes and heavy lifting.
Tired of calculating rolling pandas indicators on noisy tick data.
You want to build a trading bot in Python, Node, or Go. But calculating EMA 9/20, VWAP deviation bands, and ATR volatility manually creates memory leaks, CPU lag, and requires heavy database backfills.
Connect to our pre-calculated endpoints in 3 lines of code. Get instantaneous indicator crossovers and regime classifications in under 50ms without writing pandas math.
"Build trading bots 10x faster without computing math from scratch."
Enterprise data feeds cost $500/mo before you have paying users.
You are building a stock/crypto screener, Telegram alert channel, or trading dashboard. Polygon, Bloomberg, and Refinitiv want hundreds of dollars per month, burning your startup runway.
KustomCode gives you clean REST & WebSocket indicators, regime states, and active signals for just $9.99/mo (~R180 ZAR). Predictable pricing with zero enterprise contracts.
"Launch your trading app or alert community for the price of two coffees."
Needs clean JSON data and ready-to-run Jupyter backtest templates.
Validating strategies takes days of scraping, cleaning dirty CSV data, and writing custom backtest logic before you know if an edge even exists.
Download our free Jupyter backtest notebooks, plug in our clean historical data packs, and query regime states directly via API to validate models with zero setup friction.

}5 Reasons Developers Choose KustomCode API
Everything you need for quantitative market intelligence without the enterprise pricing markup.
1. Zero Math Overhead (Pre-Calculated Alpha)
Skip calculating rolling exponential moving averages, standard deviation bands, and ATR filters on noisy raw ticks. We run the heavy math in C++/Rust and serve clean JSON.
2. Deterministic High-Expectancy Signal Feed
Access active trade setups filtered for net positive mathematical expectancy (EV_net > +0.05%), complete with entry, take-profit, stop-loss, and calculated win probabilities.
3. Sub-100ms Low-Latency WebSockets
Stream live indicator updates and execution triggers directly into your execution engine with sub-100ms dispatch. Never miss a breakout due to polling lag.
4. Insanely Affordable ($9.99/mo ~ R180 ZAR)
