[ AlgoChart ] - Pearson Index CorrelationCorrelation Indicator (Pearson Index)
The correlation indicator measures the strength and direction of the relationship between two financial assets using the Pearson Index.
Correlation values range from +100 to -100, where:
+100 indicates perfect positive correlation, meaning the two assets tend to move in the same direction.
-100 indicates perfect negative correlation, where the two assets move in opposite directions.
The neutral zone ranges from +25% to -25%, suggesting that the asset movements are independent, with no clear correlation between them.
Interpreting Correlation Levels:
Correlation above +75%: The two assets tend to move similarly and in the same direction. This may indicate a risk of overexposure if both assets are traded in the same direction, as their movements will be very similar, increasing the likelihood of double losses or gains.
Correlation below -75%: The two assets tend to move similarly but in opposite directions. This correlation level can be useful for strategies that benefit from opposing movements between assets, such as trading pairs with inverse dynamics.
Practical Use of the Indicator:
Risk management: Use the indicator to monitor asset correlations before opening positions. High correlation may indicate you are duplicating exposure, as two highly correlated assets tend to move similarly. This helps avoid excessive risk and improves portfolio diversification.
Statistical Arbitrage: During moments of temporary decorrelation between two assets, the indicator can be used for statistical arbitrage strategies. In such cases, you can take advantage of the divergence by opening positions and closing them when the correlation returns to higher or positive levels, thus potentially profiting from the reconvergence of movements.
While the correlation indicator provides valuable insights into asset relationships, it is most effective when used in conjunction with other concepts and tools. On its own, it may offer limited relevance in trading decisions.
Spreadtrading
Arbitrage SpreadThis indicator helps to find spreads between cryptocurrencies, assess their correlation, spread, z score and atr z score.
The graphs are plotted as a percentage. Because of the limitation in pine tradingview for 5000 bars a period was introduced (after which a new starting point of the graph construction will be started), if you want it can be disabled
The multiplier parameter affects only the construction of the joint diagram on which z score and atr z score are calculated (construction of the diagram is done by dividing one pair by another and multiplying by the multiplier parameter) is shown with a red line
To create a notification you have to specify the data for parameters other than zero which you want to monitor. For parameters z score and atr z score data are counted in both directions
The data can be tracked via the data window

Spread ChartThis script lets you chart a spread of a maximum of 3 tickers (one of them being the ticker in the main chart).
Y axis is the currency amount of the spread, that is calculated by this formula:
Y = PnL = quantity * price * handleValue
Y is calculated for each ticker specified, and the sum of Ys obtained is plotted.
this way it is possible to view the PnL of the spread directly.
It is necessary to specify the handle value (point value) in the script inputs (not for the main chart ticker).
A table summarizes the spread configuration, containing all inputs.
two_leg_spread_diffThis script helps you discern the relative change of each leg in a two-legged spread over a given period. The main plot is a difference in log return over the number of bars identified by the "lag" parameter. E.g. if "lag" is 10 and leg one has increased 3% over the past ten bars, while leg two has only increased 1%, the plot value is 2%. The main plot is also colored blue when leg one increases while leg two decreases on a given bar, and red if the opposite is true. This feature identifies periods where the correlation between the two legs diminishes. The one and two standard deviation of the main plot is also plotted in faint background lines. Additionally, a table indicates the percentage in which the main plot is within one standard deviation (acc 1) and two standard deviations (acc 2). Note that the standard deviation updates on each bar, so the current standard deviation is not the one used to calculate the accuracy. Rather, if there are N bars, N different standard deviation readings have been used to compute the accuracy statistics.
The inputs are:
- timeframe: the timeframe of the chart
- leg1_sym: the symbol of the first leg
- leg2_sym: the symbol of the second leg
- lag: the number of bars back to reference for computing the log return of each leg
- anchor_to_session_start: for intraday charts only, this overwrites the "lag" input so that the "lag" always sets the point of comparison to the session start. This setting is used to compute the relative change over a single session.
Nasdaq DowJones STOCH+RSIAlternative & UPDATED version of my previous indicator for spread trading.
This indicator can work pretty well also with other indices or correlated assets such as nasdaq100 and dax40.
The spikes from one side of the channel or the orizzontal lines signal a possible entry signal for a spread trading strategy.
Nasdaq DowJones RATIOThis script gives you the ratio between the Nasdaq 100 and the Dow 30 (nas100/dow30). The RSI helps you understand when one of the two indices is overbought or oversold compared to the other one. This indicator is supposed to be of help for the strategy called spread trading, which consists in shorting an asset and buying the other one.
Spread InformerThe goal of this study is to produce information about the average size of candles in the given time frame. This can be used to help dial in your market making bot spreads.
Spread PercentThis indicator shows the percent change between the highs and the lows (or optionally the open and close) of each candle. You may also set a low and a high percent threshold to better highlight the candles that exceed your desired spread percent. Red signifies low spread, green is high spread - these are unrelated to the color of the candle body. There is also the option to display a moving average of the spread percent at your desired length which is a representation of volatility over time.
This is not only helpful for historical analysis over time, but this can also be a time saver if you are trying to calculate the measured distance of a move. Save clicks - no more needing to use the measuring tool.
The settings of the indicator on the chart above are:
- Measure Candle Body Only? - No
- Highlight Thresholds? - Yes
- Thresholds Based on Moving Averages? - Yes
- Low Percent Threshold - 3.0
- High Percent Threshold - 7.0
- Show Moving Average? - Yes
- Moving Average Length - 5
SpreadTrade - CointegrationThe Cointegration strategy is to short the outperforming instrument and go long on the underperforming instrument
whenever the temporary correlation weakens which means one instrument going up and another going down.
Here, instead of two different instruments two timeframes of the same instrument are used, lower and higher.
PT_maSpreadThis indicator is designed for use with Profit Trailer's SPREAD strategies.
The user can select either EMA or SMA averages and input their own buy value settings.
It incorporates trailing values, either manual trailing values or automatically calculated values based on volatility.
