EMA Cross signal

[paulmx]

I was wondering if there was a indicator that would tell me if two ema's crossed by placing a up/down arrow on the chart? So if the 4 ema crossed above the 8 ema a up arrow would appear at the close of the candle.

The request can be fulfilled as a signal or indicator.

I recently made a similar indicator using the SMA,
it can be easily modified to support and EMA.

Of course it is possible to realize your initial request.
