indicator request

[fabdi66]

hello, I have a strategy that works as follows: there is an indicator (I also have the mq4 file) that draws a red or lime line depending on the trend. when the candle re-enters the standard bollinger bands (20; 2) and the line changes color, it enters the trend. I need an indicator that signals me, when it is necessary to enter the trend, with an arrow. thank you

meanwhile I thank you for the work done. I saw that the indicator puts the arrows every time the color changes. instead the arrow should insert it only if in the previous change of color, the candle has overtaken the lines of the standard bollinger bands. if the candle has exceeded the upper line of the bollinger band and after the colored line turns red, then it must insert the down arrow, if instead the candle has passed the lower line of the bollinger band and after the line turns green then it must insert the up arrow. thank you
