We continue to calculate the bullish engulfing condition for monthly candlesticks (engulfingConditionM) as before.
We then create two variables (engulfingConditionY and lastYear) to calculate the yearly engulfing condition.
We use an if statement to check if the year has changed compared to the previous bar. If it has, we update the engulfingConditionY variable; otherwise, we keep the previous year's value.
Finally, we plot the monthly and yearly signals on the chart.
This code allows you to work with monthly data and calculate yearly signals based on the monthly data available in TradingView. Please note that this is an approximation and not true yearly resolution data, but it's a common workaround used in TradingView Pine Script.
