[blackcat] L1 Close Histogram Oscillator

Level: 1


A histogram is a special chart that is applied to statistical data that is divided into numerically ordered groups. For example groups with close relationships in the vicinity like "Close-ref(Close ,1)", "Close-ref(Close,2)" and so on. A histogram provides a snapshot of all the data so that you can quickly get an overview of the historical data, especially its general shape.In a histogram, the bars are linked - in contrast to a bar chart for categorical data, in which the bars represent categories that are in no particular order and are separated. The height of each bar in a histogram indicates either the number of individuals (called the frequency) in each group or the percentage of individuals (the relative frequency) in each group. Each individual in the data set falls into exactly one bar.


L2 Close Histogram Oscillator is a novel overbought and oversold indicator that estimate the trend state by counting a specific bar relationship nearby. Once nearby bars reach consensus, it may spread to global quickly. The reason why I got this inspiration is because I have been engaged in the research of blockchain consensus mechanism. The market is a complex system, and its consensus depends on the common human characteristics: greed and fear. The trend of the market often also conforms to sociological characteristics. Maybe it's a bit complicated for me to say that. However, if you understand the principle of the spread of rumors and viruses, you can understand the situation where some individuals in the market have local consensus and gradually spread to the overall situation. This is the process of trend formation.

Key Signal

fastcounter --> fast close histogram counters
slowcounter --> slow close histogram counters
attention --> bottom price appears, with height of 10 in white
readybuy --> a small position buy opportunity after first bottom detected, with height of 20 in yellow
buylow --> a small position buy at low price, with height of 30 in lime
longentry --> a confirmed long entry signal by close histogram counter, with height of 40 in green
risk --> oscillator top is reached and trend reversal may happen, with height drop from 100 to 80 in red

Pros and Cons


1. since this is based on consensus formation principle, i think this is a leading indicator by spreading local consensus to global
2. it is an oscillator, overbought and oversold can be easily observed.


1. the model is not complex enough to depict market behavior exactly.
2. sideways and chop market will make this indicator's output hard to read.


This is rare! I combined my previous theory of developing cellular automata with the market to produce such a weird indicator. I hope to inspire everyone and study market behavior in a deeper level.


In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts.

The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works.

Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element.

Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level.

Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated.

Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.

Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.
