Hidden Markov Model Market Regimes [LuxAlgo]The Hidden Markov Model Market Regimes tool provides a probabilistic framework for identifying the current state of the market by applying a Hidden Markov Model (HMM) to price action and volatility data.
🔶 USAGE
The indicator identifies four distinct market regimes. Each regime is represented by a unique color, and the oscillator values (0-100%) represent the probability of the market being in that specific state.
🔹 Regime Breakdown & Trading Implications
Low Volatility Trend (Gray): Characterized by steady, consistent returns with minimal price swings. Ideal for trend-following strategies and "buy-and-hold" positions.
High Volatility Chop (Orange): Large price swings without a clear directional trend. Suggests a "risk-off" environment or mean-reversion strategies.
Crash Regime (Red): Extreme negative returns coupled with a spike in volatility. Indicates high panic; traders may look for hedging opportunities.
Accumulation (Blue): Low volatility with neutral-to-rounding price action. Often occurs at the end of a bear cycle, signaling a potential "bottom-fishing" zone.
🔹 Visual Cues
The indicator features background highlighting that changes based on the "Dominant State" (the state with the highest current probability).
When a specific probability line crosses above the 50% "Neutral" line, the model is gaining conviction. Crosses above 80% indicate "High Confidence" in that regime. Users should watch for "probability flips," where one regime's dominance is rapidly overtaken by another, signaling a structural shift in the market.
🔶 DETAILS
The script implements a specialized version of the Forward Algorithm to estimate the likelihood of hidden states.
🔹 Heuristic vs. Trained ML
It is important to note that this indicator is accurately described as a "Heuristic" or "Static" HMM rather than a traditional Machine Learning model. Unlike modern ML models that require extensive training on historical datasets (using algorithms like Baum-Welch or Expectation-Maximization), this model uses fixed mathematical parameters and predefined heuristic-based emission profiles.
This approach ensures deterministic behavior—the model will always react to the same price patterns in the same way—and eliminates the "black box" nature of traditional ML while still providing the probabilistic benefits of a Markov chain.
🔹 Mathematical Logic
Log Returns: The model utilizes log returns ( TSX:LN (Close_{t} / Close_{t-1})$) rather than simple percentage changes to ensure time-additivity and a more symmetric distribution of data.
Emission Likelihoods: The model uses Gaussian-style probability density functions to compare normalized returns and volatility against "ideal" profiles for each state. For example, the Crash Regime likelihood increases when returns are significantly below the mean and volatility is significantly above the mean.
Transition Matrix (Markov Property): This defines the "memory" of the system. The matrix is weighted toward "persistence" (diagonal values), meaning the market is statistically more likely to stay in its current regime than to jump to a different one every bar.
🔶 SETTINGS
🔹 HMM Settings
Lookback Period: The window used to calculate the mean and standard deviation for normalizing returns and volatility.
Learning Rate: Controls how quickly the model updates its internal probabilities. Range: 0.01 (very slow/stable) to 1.0 (instant/reactive).
🔹 Dashboard
Enable Dashboard: Toggles the visibility of the on-screen information table.
Position: Determines where the dashboard is anchored (Top Right, Bottom Right, or Bottom Left).
Size: Adjusts the scale of the dashboard text and cells.

Cryptos Pump Hunter[liwei666]🔥 Cryptos Pump Hunter captured high volatility symbols in real-time, Up to 40 symbols can be monitored at same time.
Help you find the most profitable symbol with excellent visualization.
🔥 Indicator Design logic
🎯 The core pump/dump logic is quite simple
1. calc past bars highest and lowest High price, get movement by this formula
" movement = (highest - lowest) / lowest * 100 "
2. order by 'movement' value descending, you will get a volatility List
3. use Table tool display List, The higher the 'movement', the higher the ranking.
🔥 Settings
🎯 2 input properties impact on the results, 2 input impact on display effects, others look picture below.
pump_bars_cnt : lookback bar to calc pump/dump
resolution for pump : 1min to 1D
show_top1 : when ranking list top1 change, will draw a label
show pump : when symbol over threhold, draw a pump lable
🔥 How TO USE
🎯 only trade high volatility symbols
1. focus on top1 symbol on Table panel at top-right postion, trading symbols at label in chart.
2. Short when 'postion' ~ 0, Long when 'postion' ~ 1 on Table Cell
🎯 Monitor the symbols you like
1. 100+ symbols added in script, cancel remarks in code line if symbol is your want
2. add 1 line code if symbol not exist. if you want monitor 'ETHUSDTPERP ', then add
" ETHUSDTPERP = create_symbol_obj('BINANCE:ETHUSDTPERP'), array.unshift(symbol_a, ETHUSDTPERP ) "
🎯 Alert will be add soon, any questions or suggestion please comment below, I would appreciate it greatly.
Hope this indicator will be useful for you :)
enjoy! 🚀🚀🚀

Levels Of Fear [AstrideUnicorn]"Buy at the level of maximum fear when everyone is selling." - says a well-known among traders wisdom. If an asset's price declines significantly from the most recent highest value or established range, traders start to worry. The higher the drawdown gets, the more fear market participants experience. During a sell-off, a feedback loop arises, in which the escalating fear and price decline strengthen each other.
The Levels Of Fear indicator helps analyze price declines and find the best times to buy an asset after a sell-off. In finance, volatility is a term that describes the degree of variation of an asset price over time. It is usually denoted by the letter σ (sigma) and estimated as the standard deviation of the asset price or price returns. The Levels Of Fear indicator helps measure the current price decline in the standard deviation units. It plots seven levels at distances of 1, 2, 3, 4, 5, 6, and 7 standard deviations (sigmas) below the base price (the recent highest price or upper bound of the established range). In what follows, we will refer to these levels as levels of fear.
HOW TO USE
When the price in its decline reaches a certain level of fear, it means that it has declined from its recent highest value by a corresponding number of standard deviations. The indicator helps traders see the minimum levels to which the price may fall and estimate the potential depth of the current decline based on the cause of the actual market shock. Five-seven sigma declines are relatively rare events and correspond to significant market shocks. In the lack of information, 5-7 sigma levels are good for buying an asset. Because when the price falls that deep, it corresponds to the maximum fear and pessimism in the market when most people are selling. In such situations, contrarian logic becomes the best decision.
SETTINGS
Window: the averaging window or period of the indicator. The algorithm uses this parameter to calculate the base level and standard deviations. Higher values are better for measuring deeper and longer declines.
Levels Stability: the parameter used in the decline detection. The higher the value is, the more stable and long the fear levels are, but at the same time, the lag increases. The lower it is, the faster the indicator responds to the price changes, but the fear levels are recalculated more frequently and are less stable. This parameter is mostly for fine-tuning. It does not change the overall picture much.
Mode: the parameter that defines the style for the labels. In the Cool Guys Mode , the indicator displays the labels as emojis. In the Serious Guys Mode , labels show the distance from the base level measured in standard deviation units or sigmas. Indicator

Cash in/Cash out Report (CICO) - Quiets market noiseThe cash in/cash out report (CICO for short) was built with the intent to quiet the market noise. The blunt way to say it, this indicator quiets the market manipulators voice and helps the retail investor make more money. I believe money is better of in the 99% hands versus the greedy hoarding that is currently going on. There are dozens of companies in the SP500 that have the same tax rate as unborn babies, nada. These hoarders also have machine learning high frequency trading bots that purposely create fear and anxiety in the markets. When all of the major markets move at the exact same time of day on frequent occasions, I see red flags. I recommend looking into Authorized participants in the ETF market to understand how the markets can be manipulated, specifically Creation and Redemption.
Enough of my rant. This indicator is open source. Directions on how to use the indicator can be found within the code. The basic summary is, clear your charts to bare minimums. Make the colors gray on all candles. Then apply this indicator. The indicator will color the "buy" and "sell" signals on the chart. Keep in mind, markets are manipulated to create fear in the retail investors little heart and can change drastically at any second. This indicator will show real time changes in running sum into and out of the market, it is estimated by average prices and not exact.
Once the chart is all greyed out and the indicator is applied you will see an area colored red and green. What this indicator does is takes a running sum of the new money into and out of the market. It takes the average of the high and low price times the volume. If the price is going up the value is positive, going down will be negative. Then the running sum is displayed. The area section is the running sum and the column bars are each value. When a market is steadily increasing in value you will see the large green area grow. When markets shift, values and display will change in color and vector. Full descriptions are available within the script in the comment sections.
I hope this help you make more money. If this helps you grow profits, give it a like!
Happy investing 99%er! Indicator
