In software development, we handle edge cases. In financial markets, Christmas Eve is an edge case.
Today, the Jakarta Stock Exchange (IDX) remained open, but the data feed tells a warning story. The trading volume plummeted to 15.54B shares, a ~53% drop day-over-day.
For those of us who build trading systems or trade manually based on technicals, this presents a "Null Liquidity" problem.
The Bug in the System: Most technical indicators (RSI, MACD, Moving Averages) rely on standard volume participation to be valid. When volume disappears:
False Signals: A small buy order can spike the price artificially because there are no sellers to absorb it.
Slippage: The gap between your OrderPrice and ExecutionPrice widens significantly.
Volatility Traps: Low liquidity environments are prone to "stop hunts."
The Macro Exception: While equities are in a System.Sleep() mode, the commodities API is firing. Gold spot price punched through $4,500 today. This is a raw signal of "risk-off" sentiment heading into 2026.
The Code for Today: The best function you can run today is not Buy() or Sell(), but Wait(). I am using this downtime to refactor my thesis for Q1 2026. If you treat trading like engineering, you know that uptime is important, but maintenance windows are critical.
Consider today a maintenance window.
