Como incluir um alerta visual?

[fernando9272]

Boa noite! Venho utilizando faz bastante tempo esse indicador de bolinha e ele não repinta, mas aparece no topo ou fundo após confirmado.

Como faço para inserir uma indicação visual em qual candle a bolinha apareceu?

Se você não sabe programar em MQL5, você terá que contratar um programador...
