Requesting help with alert on custom indicator

[tabla]

This custom indicator gives intraday bullish and bearish signals.

But there are two issues
1. if Alerts are set up by doing a 'create alert' by right clicking on the indicator) the mobile push alerts don't fire correctly. They seem to be triggering off seemingly randomly and don't align with the visual onscreen up/down arrows the visuals work fine on the chart (i.e. up/down arrows). Interestingly - the on-screen alerts work fine (by using createalert thinkscript statements work fine too)

2. the indicator and arrows doesn't display on a mobile device (when debugging, it seems to fail to render on the lindev statement)

Would really appreciate your feedback and a fix to the above two issues! I am pasting the custom indicator thinkscript below
Use on a 2 min chart for SPY -->

Thanks in advance for your help!!
