//The provided script is an indicator for TradingView written in Pine Script version 5. The indicator is used to determine entry and exit points for a trading strategy. Here's a detailed breakdown of what the script does:

// Strategy Definition:

// Bannos Strategy is the full name, with a short title Bannos.
// The overlay=true option indicates that the strategy will be overlayed on the price chart.
// Tracking Entry Month:

// A variable lastEntryMonth is set up to track the month of the last entry.
// currentMonth identifies the current month.
// Trend Regularity Adaptive Moving Average (TRAMA):

// It takes an input of length 99 as default.
// It uses adaptive calculations to track trend changes.
// Trendlines with Breaks:

// Identifies local peaks over a given period (in this case, 14) and calculates a slope based on these peaks.
// Relative Strength Index (RSI):

// Uses a length of 14 (default) to calculate the RSI.
// RSI is an oscillation indicator that indicates overbought or oversold conditions.
// Strategy Logic for Long Entry:

// A long position is opened if:
// The close price is above the TRAMA.
// There's a crossover of the close price and the upper trendline.
// The position is taken only once per month.
// Strategy Logic for Long Exit:

// The long position is closed if the RSI exceeds 70, indicating an overbought condition.
// Plotting:

// The TRAMA is plotted in red on the chart.
// A horizontal line is also drawn at 70 to indicate the RSI's overbought zone.
// In summary, this strategy aims to enter a long position when certain trend and crossover conditions are met, and close the position when the market is considered overbought as per the RSI. Additionally, it ensures entries only occur once a month.
//

ph = ta.pivothigh(length_trend, length_trend)
upper = 0.

// Parameters for RSI

// Strategy Logic for Long Entry

    strategy.entry('Long', strategy.long)

// Strategy Logic for Long Exit
