Reference to indicator crossover barsAgo

[Novicetrader]

Hi, I want to find the value of indicator crossover exactly 2 bars ago, look back period won't work since it counts current bar up to the look back period.

I know indicators can be reference like SMA(20)[2] to find the value 2 bars ago. But I have problem applying it to indicator crossovers.

I tried:
if (CrossAbove(T3(1, 2)[2].Plot1, T3(1, 4)[2].Plot1, 1))
if (CrossAbove(T3(1, 2).Plot1[2], T3(1, 4).Plot1[2], 1))
if (CrossAbove(T3(1, 2).Plot1, T3(1, 4).Plot1, 1)[2])

All returned with syntax error, what's the method to program it?

Thanks in advance.

Not sure I follow, CrossAbove() returns either true or false. It does not return a value.

I tried:
if (CrossAbove(T3(1, 2)[2].Plot1, T3(1, 4)[2].Plot1, 1))
if (CrossAbove(T3(1, 2).Plot1[2], T3(1, 4).Plot1[2], 1))
if (CrossAbove(T3(1, 2).Plot1, T3(1, 4).Plot1, 1)[2])

While it may not accomplish what you want, the syntax error is due to the forced index (ie [x], [1], [2] etc) which cannot be used in CrossAbove/Below.

CrossAbove(T3(1, 2).Plot1, T3(1, 4).Plot1, 1))

would be the correct way to re-write your first example. It says if T3(1, 2).Plot1 crosses above T3(1, 4).Plot1 within the last 1 bar, then 'true' otherwise false. If you want it to be within 4 bars change the very last number from 1 to 4, for instance.

If you want to find out if it crossed within 10 bars, but want to exclude anything that crosses within the last 2 bars, this would do it:

CrossAbove(T3(1, 2).Plot1, T3(1, 4).Plot1, 10))
&& !CrossAbove(T3(1, 2).Plot1, T3(1, 4).Plot1, 2))

first line says everything in 10 bars, second line says except within 2 bars.

Oh and this may help as well:

if T3(1, 2).Plot1[3] < T3(1, 4).Plot1[4] // 3 bars ago was less than 4 bars ago
&& T3(1, 2).Plot1[2] > T3(1, 4).Plot1[3] // 2 bar ago was more than 3 bars ago

Thanks ctrlbrk, excluding recent 2 bars will serve my purpose. Got to love this forum, I learn something new everyday.
