The problem

Most retail traders in Indonesia
never test their strategy.

Ideas come from Telegram groups, YouTube and gut feeling. Testing them properly takes code, clean data and time that most people do not have.

Gut feeling is expensive

Trading a rule you have never tested means discovering its weak spots with real money.

Backtesting tools need code

Python libraries and Pine Script are powerful, but most investors are not programmers.

Global tools ignore IDX

Lot sizes, fees, rights issues and thin liquidity on small caps make IDX different. Generic tools get it wrong.

The ESI suite

One workspace for the whole trade.

Test ideas on the past, scan today's market, manage risk across your portfolio, and learn from every closed position. Five tools, built for IDX, sharing one data engine.

Building now

Backtest Studio

Validate strategies against history

Test any idea on years of IDX data with 100-share lots, stop losses and trailing stops. Try custom indicator combinations and tune for win rate and drawdown, not just profit.

ESI Copilot

An analyst that speaks your language.

Every ESI tool has an AI copilot built in. Ask in plain English or Bahasa Indonesia; the copilot turns it into precise rules, our engine does the math, and the copilot explains what it found.

  • Build. Describe a strategy or a scan in words and get editable rules, checked against the indicators ESI supports.
  • Explain. Understand why a backtest won or lost, and what a portfolio change does to your risk.
  • Coach. Get variations worth testing and patterns from your own trade history you would not spot alone.
