                "salmon"
          )
The problem I have is that I made the indicator generate a sell or buy signal every time a candle turns red or green, since the next candle is usually the same color, what I want is for the signal not to be generated on all candles in the trend. I want it to be plotted only on the first candle in the trend of bars which are painted by the indicador.

'use nan.

or

drop_plot_value('i don't want', current_bar_id) drop_plot_value('i don't that', current_bar_id) drop_plot_value('i don't this', current_bar_id)`
