What is 4-Bell?

4 Bell makes use of Machine Learning techniques in combination with TA tools such as indicators, oscillators and chart patterns. As you can see, 4 Bell consists of 2 bells. The right bell’s mouth indicates the selling range, and the left bell’s mouth shows the buying range. Users can use 4 Bell to Observe market behaviour and get the confirmation they need for their decisions. All traders can use this indicator, regardless of their experience.

As you can see, each bell is divided in half by a horizontal line. The upper half analysis the market based on TA tools, while the lower half relies on data science and AI methods such as deep learning and machine learning to do the same.

The upper half consists of 18 boxes and the strength of TA tools increases gradually, with 18 being the strongest, while the lower half calculates the strength of the trade using AI, and represents it in 4 stages. A reliable zone is a zone where both levels are showing signals, and it’s only then that the zone changes color and can be considered valid.

The grey zone between the two bells is called Hover Zone and shows indecision in the market. Professional traders stop their trading activities in this area, and wait for more confirmations.

Moving to the right: the sell bell

When the price enters the Start Zone, trades should pay more attention to the market movements and prepare proper risk management techniques as well as market analysis and selling strategy.

The right bell’s mouth is called Decision Zone and is the first stage in a multi-stage selling strategy. After the first stage, traders can expect a market reversal, or otherwise, the zone moves on to the next stage. Based on the asset management techniques, traders can sell 5-15% of their holdings in this zone.

Golden Zone is the most valuable and valid zone for selling or simply exiting the market. Based on the advanced asset management techniques, it is advised to sell up to 50% of the assets in this zone. Existing this zone may indicate a change in trading structure of the market, and that an unexpected and critical situation may be on the way.

Glut Zone rarely happens in higher timeframes and Traders should keep in mind that keeping their positions open in this zone is quite risky as it shows overbought or oversold conditions, and a market reversal is highly possible. As this zone is seen in highly volatile market conditions, long shadows may form. Observing this zone in the red area (right bell’s mouth) gives trades the permission to sell all their assets or enter a short position.

Moving to the left: the buy bell

When the price is in the Start Zone, trades should pay more attention to the market movements and prepare proper risk management techniques as well as market analysis and buying strategy.

The left bell’s mouth is called Decision Zone and is the first stage in a multi-stage buying strategy. Traders can expect a market reversal simultaneously, and take the necessary steps to buy, in case the zone moves on to the next stage. Based on the asset management techniques, traders can buy 5-15% of their holdings in this zone.

Golden Zone is the most valuable and valid zone for buying or simply entering the market. Based on the advanced asset management techniques, it is advised to buy up to 50% is this zone. Existing this zone may indicate a change in trading structure of the market, and that an unexpected and critical situation may be on the way.

Glut Zone rarely happens in higher timeframes and Traders should keep in mind that keeping their positions open in this zone is quite risky as it shows overbought or oversold conditions, and a market reversal is highly possible. As this zone is seen in highly volatile market conditions, long shadows may form. Observing this zone in the green area (left bell’s mouth) can be considered as the stop-loss.

How this version is computed

The upper half reads six indicators: RSI, Stochastic, Williams %R, CCI, Money Flow and Bollinger %B. Each has three stretch levels. When price is stretched down a level counts toward the buy bell, when stretched up toward the sell bell, and opposite levels cancel. The net count is the strength, from 0 to 18.

The lower half is four checks in the direction of the reading: the next higher timeframe leans the same way, volume is at least 1.3 times its 20-candle average, MACD momentum is turning back, and the candle closed in the half of its range that points to a turn.

A zone is valid only as far as both halves reach. Strength 11 is the Golden zone, but with two checks it counts only as Decision. Only closed candles are read, so a reading never changes while its candle is still open.

The original 4-Bell described its lower half as a machine-learning stage. That model is not available to the new Tralyzer, so this version uses the four checks above. Everything is shown on this page so you can see why each reading says what it says.

Measured on 7 Nov 2026 over the last 1,500 candles of all 20 markets: on every timeframe, valid readings went their way 50 to 55% of the time, and looser or stricter levels did no better. 4-Bell describes how stretched the market is; it does not predict the next move.

Why it is called 4-Bell

Ancient warriors used bell-shaped tools which could produce different sounds. Every sound was the indication of a specific war condition and tactical formation, and the expected reactions to those situations. If the soldier responded only once using the tool, it meant he/she is still on the watch and has the situation under control. If the soldier responded twice, it meant the tactical formation of the enemy is changing and they’re moving their military equipment around. Responding three times was an indication that the war has begun, or the troops have the permission to attack. And at last, they would respond 4 times if the commander wanted to use the full force in order to finish the war. This strategy inspired us to develop 4Bell indicator.
