Multiple Patterns

[Timothy_Miller]

Hello,

I have been for at a road block with an indicator and I on the hunt to create Multiple Patterns on a Chart Simultaneously.
Given a New Code of...

OnBarUpdate()
{
DrawTriangle("Triangle", true, 0, High[0], -1, Low[-1], -2, High[-2], Color.White, Color.White, 1);
DrawTriangle("Triangle", true, 0, High[0], -2, Low[-2], -4, High[-4], Color.White, Color.White, 1);
}

Where the CurrentBar will print to the Right Every other or Ever two Candles.
I have the Suspicion that the Code is ONLY printing the MOST updated Pattern. (i.e. the Lower One.)
Any Ideas will be greatly appreciated.

Your triangles have the same tag, so the last one will overwrite any others. Make your tags unique.

The syntax in the NTHelp states this rather clearly.

Hello Timothy,

koganam is correct in his reply -- as long as you are using the same tag for both triangles, the second one will always update the first one, rather than drawing a new triangle.

However, I will add this to koganam's reply: In order to assign a unique tag to each triangle, you will need to find a way to assign a value that can be updated on each bar. For example, something like ("Triangle" + CurrentBar) will result in unique tags that include the current bar number ("Triangle233," Triangle234," etc.).

Please let me know if I can assist further.

Dear NinjaTrader_David and koganam,

Both of your ideas have worked and I am still amazed at how it was such a simple fix.
Also I have the DrawTriangle() in a for() Loop and prints different Values for each point.
Again, thank you very much.

Simplified version...

for (...)
{
DrawTriangle("Triangle1" + CurrentBar, ...)
DrawTriangle("Triangle2" + CurrentBar, ...)
}

I am using a pair of triangles for each successful loop.
