RSI 50% planZ

RSI Settings:

RSI Length: The Relative Strength Index (RSI) is calculated using the specified length. In this code, the value 89 is set as the RSI length.
Level 50: Level 50 is considered a neutral level, representing a balance of momentum between bullish and bearish trends.
Buy and Sell Conditions:

Buy Signal: A buy signal is generated when the RSI crosses from below to above level 50.
Sell Signal: A sell signal is generated when the RSI crosses from above to below level 50.
Drawing on the Candle:

When a buy or sell signal occurs, a box is drawn around the candle that represents the signal.
A line is extended through the middle of the candle between the high and low values. This line is drawn through the midpoint of the candle to highlight the position.
Background Color Change:

The background color of the chart is changed based on the signal:
Green for a buy signal.
Red for a sell signal.
How the Indicator Works:
RSI is calculated using the 89-period length, and it watches for a crossover of the 50 level:
If RSI crosses above 50 from below, a buy signal is plotted below the candle.
If RSI crosses below 50 from above, a sell signal is plotted above the candle.
A box is drawn around the candle with the signal, and a line is extended across the middle of the candle to highlight the position.
The background of the chart changes based on the signal (green for buy, red for sell).
Adjustable Features:
You can adjust the RSI Length in the indicator settings to change the period for RSI calculation.
Usage:
This indicator is useful for identifying momentum shifts in the market.
Traders or investors can use it to determine buy and sell points based on RSI crossovers.
