What is バイアス?

バイアス指標（Bias）は、テクニカル分析で使用されるモメンタム指標です。価格のモメンタム、トレンドの方向性、またはボラティリティを分析することにより、トレーダーが潜在的なエントリーポイントとエグジットポイントを特定するのに役立ちます。

Signal Types

Overbought / Oversold

When BIAS reaches historical extreme positive levels, the asset is overbought; extreme negative levels indicate it is oversold.

Zero Line Crossover

A cross above zero indicates price has moved above the MA (bullish), while a cross below zero indicates price has dropped below the MA (bearish).

Divergence

When price makes a new high but BIAS fails to do so, it suggests weakening momentum and a potential trend reversal.

FAQ

What are the standard 'extreme' levels for BIAS?

There are no universal levels, but for a 12-day BIAS, +/- 5% is often considered significant for stocks, while +/- 3% might be used for less volatile indices.

How does BIAS differ from the Moving Average itself?

The Moving Average shows the average price level, while BIAS quantifies the distance between the current price and that average as a percentage.

Can BIAS be used in a strong trending market?

In strong trends, BIAS can stay at extreme levels for a long time. It is safer to use it for mean reversion in ranging markets or as a secondary confirmation in trends.
