🔶 USAGE

The proposed script can allow users to quickly determine if a specific day/month is considered bullish or bearish. A green cell is used for bullish days/months, while a red one is used for bearish days/months.



Additionally vertical lines are displayed on new days/months with a color highlighting the current sentiment for this specific day/month. Note that this is done retrospectively, the color of a line set at time t might differ at time t+n.

🔶 SENTIMENT METHODS

Determining whether a day/month is bullish or bearish can be done using three different methods. Note that each method makes use of the closing price as the input, and as such can eventually return different results depending on the selected timeframe. Each method is described below:

🔹 Linreg



The Linreg method fit lines between each day/month using the method of least squares and determines if that particular day is bullish or bearish based on the line slope sign. For example, a rising line would indicate a bullish day/month.

🔹 Accumulated Deltas

The method of accumulated deltas simply accumulates bullish and bearish price changes for the current day/month, the result with the highest magnitude determines the sentiment for that day/month.

🔹 Max/Min



The max/min method computes a trailing maximum and a trailing minimum for the current day/month. The sentiment is determined by the price position relative to the average between the obtained maximum/minimum, with a bullish sentiment being determined if price is above the average.
