Buy/Sell Box

This indicator tries to identify the points where the price exceeds or falls below a rectangle based on the opening and closing prices of the previous period, the creation of the boxes occurs when a doji is detected therefore it will calculate the coordinates of the rectangle that will be drawn around it, therefore the indicator offers buy or sell signals based on this logic. Specifically, the buy signal is generated if the closing price is above the top of the rectangle and satisfies some previous price conditions while the sell signal is generated if the closing price is below the bottom of the rectangle and satisfies some conditions of previous prices within a further threshold based on the Ema 150.
Lines are then drawn on the graph to visually display the extreme price levels, which can be useful for any confirmation of buy and sell signals, Stop Loss and Take Profit, Trend Filter (to visually understand if the trend is bullish or bearish)

A potentially effective trading strategy could involve identifying buy and sell signals near the extreme price level lines drawn by the indicator. This approach can be used to try to improve the accuracy of your trading signals and make more informed decisions. For example:
When you receive a buy or sell signal based on the dojis and rectangles generated by the indicator, check whether the price is also near one of the extreme price level lines. If you are receiving a buy signal and notice that the current price is near a low of the lower level line, this may further confirm the buying opportunity, as the price is near a significant resistance level. On the contrary, if the sell signal was close to a maximum price level it could confirm an excellent short entry.
It is also possible to use the boxes as reference points to set the stop loss and take profit levels. If you are entering a buy position, you might consider setting your stop loss just below an upper line of the last box. Additionally, you may want to set your take profit near a higher price level if you are looking to maximize profits. This will help manage risks and protect your capital.
