When the world sleeps, your capital grows. 3C Overnight is an intelligent overnight momentum strategy designed to capture hidden opportunities.

Inspiration
The 3C Overnight Strategy is based on a quick and efficient pattern. It aims to capitalize on nighttime price movements while minimizing daytime market noise. By focusing on simple and effective price patterns, the strategy seeks to exploit inefficiencies in price behavior.
Key Components
The strategy uses a multi-day price pattern to identify investment opportunities.
It is based on simple entry rules and one exit rule.
It limits risk by exiting very quickly without setting rigid Stop Loss or Take Profit levels.
Backtest 1, Fixed $ Money Management
As part of this test variant, a fixed amount of $100,000 was invested.
Initial capital: $100,000
Test period: 1994 - 06.2025 (30 years)
Tested index: SPY

Backtest 2, % Money Management
In this backtest, we invest in a strategy that constantly uses 100% of the current capital (starting with $100'000). This means that as the capital grows or decreases, the position value changes proportionally. The rest of the parameters remain unchanged.

The 3C Overnight Strategy, despite having a lower CAGR compared to SPY, can still generate approximately a 33% annual profit when considering the capital at risk. This is due to its minimal capital requirements. In an ideal portfolio of similar strategies, it performs three times better than the benchmark.
The equity chart for this test looks as follows.
The chart includes a benchmark, which is a thin yellow line.
