Hi
I have tried over the last few days to build a simple crossover indicator with alerts using various chat bots . But I have come to the simple resolution that none of us [me & bots ] have skills to make it work . So what do I require
I want a custom 13 day moving average to crossover either an Adaptive ma /Hull ma { my attempts involved using a Hull but either is fine } and to send me an push notification via txt on crossover simple as that .
Below are my attempts the txt me version uses a Twillo number i,m thinking that may not be necessary i,ll let you tell me what you think
1 st crossover
