Question 1

How to connect techan to a live exchange like Binance?

Accepted Answer

Techan doesn't include built-in exchange connectors. You need to use external libraries or APIs to fetch data, format it into candlestick structures using techan.NewCandle, and update the TimeSeries manually, as shown in the Quickstart with hardcoded data.

Question 2

Techan vs ta4j for technical analysis?

Accepted Answer

Techan is inspired by ta4j but is native to Go, offering idiomatic APIs and performance benefits for Go ecosystems. Ta4j is Java-based with a larger feature set and community, so Techan is better for Go-specific projects but may have fewer advanced indicators.

Question 3

How to backtest a trading strategy with techan?

Accepted Answer

Use the RuleStrategy framework to define entry and exit rules, then iterate over historical data in a TimeSeries to simulate trades. Record trades with TradingRecord and analyze results using the built-in profit and trade analysis tools, as demonstrated in the strategy example.

Question 4

Does techan support real-time data analysis?

Accepted Answer

Techan can handle real-time data if you continuously update the TimeSeries with new candlesticks, but it lacks built-in streaming or event-driven features, requiring custom implementation for low-latency applications.

Question 5

What indicators are available in techan besides EMA?

Accepted Answer

Techan includes basic indicators like close price and cross rules, but the README primarily highlights EMA. For a full list, you'd need to explore the source code, as documentation is sparse on other indicators such as RSI or MACD.

Question 6

How to calculate RSI with techan?

Accepted Answer

Techan doesn't have a built-in RSI indicator. You would need to compute it manually using the available price indicators and Go's math libraries, or extend the library by creating custom indicator implementations based on the framework.
