The PCR, or Put Call Ratio, is a technical analysis indicator that is used to measure the sentiment of the options market. It is calculated by dividing the total number of put options that are outstanding by the total number of call options that are outstanding. A high PCR indicates that there are relatively more put options outstanding compared to call options, which may be a sign of bearish sentiment in the market. On the other hand, a low PCR indicates that there are relatively more call options outstanding compared to put options, which may be a sign of bullish sentiment in the market.

A PCR graph is a visual representation of the PCR over a specific period of time. It typically consists of a line chart that plots the PCR on the y-axis and the time period on the x-axis. The PCR graph can be used to analyze the market sentiment and to identify trends and patterns in the options market.
To define a PCR graph in the share market, it is helpful to understand the different terms and concepts that are used in technical analysis and options trading. Some of the key elements that are typically included in a PCR graph include:
X-axis: The x-axis of the PCR graph represents the time period over which the PCR is being plotted.
This can be a specific number of days, weeks, or months, depending on the desired time frame.

Y-axis: The y-axis of the PCR graph represents the PCR, which is calculated by dividing the total number of put options that are outstanding
Data points: The data points on the PCR graph represent the PCR at specific points in time. Each data point is connected to the previous data point by a line, creating a line chart.
Trend lines: Trend lines can be added to the PCR graph to help visualize the overall trend in the market and to identify potential trading opportunities.
Moving averages: Moving averages can be added to the PCR graph to help smooth out short-term fluctuations and to identify long-term trends in the market.

The PCR graph can be a useful tool for investors and traders who are looking to understand the market sentiment and to identify potential trading opportunities. It is important to note, however, that the PCR graph is just one factor to consider when evaluating the market and that it should be used in conjunction with other technical and fundamental analysis tools.
