Here is another small contribution from myself as requested by Maroka.

ZZ Take Profit Alert indicator, the default settings match the v15 ZZ 3 line. It draws a ZZ line on the chart but if you set the colour to none it won't appear, apart from that it draws nothing on the chart. It does however give alerts on your computer, email and/or notifications. It will do this at the start of every new bar when the ZZ line has moved to a new high/low in the previous bar.

This is a completely stand-alone indicator, I tried using the v15 ZZ but it would not play nicely.
