too many drawing objects

[duck_CA]

is there a way to filter or keep the drawing objects (triangles in this example) from popping up once the criteria has been met?
maybe another "x amount" of bars required to start drawing again...


if ((High[0] >= SMA(89)[0])
&& (High[0] >= KeltnerChannel(1.5, 22).Lower[0] + -2 * TickSize)
&& (SMA(89)[0] <= EMA(22)[0] )
&& (Diff[1] >= 0)
&& (Stochastics(5, 3, 3).K[1] <= stokl || Stochastics(5, 3, 3).K[2] <= stokl
|| Stochastics(5, 3, 3).K[0] <= stokl)
)
DrawTriangleUp(Time[0].ToString(), 0, Low[1] - 5.25* TickSize, Color.Yellow);

you could add a custom flag variable like:
- only draw if condition are met and flag is false
- set flag to true if drawn

-> won't draw again after flag is set
