Pine Script v5, EMA clouds and alerts

Question

Trying to learn Pine script here to optimize my trading strategy. I have around 1.5 year of experience trading. The trendsystem Im using is the all mighty Ripster Clouds. It is based on several EMAs moving, and making a cloud(like a ichimoku cloud) and spotting trend reversing. I'll link paste the code below.

What Im struggling with is adding alerts and arrows pointing where the trendreversing start, and where it ends.

Bull = When EMA cloud 2 crosses OVER EMA cloud 3

Bear = When EMA cloud 3 crosses UNDER EMA cloud 3.

I also want a variable of what timeframe it is based upon. My suggestions are 3min, 10min, 1hour, 1 day and 1 week.

If anyone can either point me in a direction to get help, or help me in the comments, it will be greatly appreciated.

The code will be free of course.

Screenshot where the clouds change. Cloud 2 = 5-13 EMA cross, Cloud 3 = 34-50 EMA cross

Answer 1

There are a few ways you can calculate a crossover or crossunder of these clouds from a TA perspective.

First is waiting for the entire cloud 2 to crossover cloud 3; this can be done by using the crossover of the slower MAs in each cloud.

bull_signal = ta.crossover(htf_ma4, htf_ma6)
bear_signal = ta.crossunder(htf_ma4, htf_ma6)

Second is getting the crossover signal as soon as the clouds begin to crossover or under. In this case you would use the faster MAs in each cloud.

bull_signal = ta.crossover(htf_ma3, htf_ma5)
bear_signal = ta.crossunder(htf_ma3, htf_ma5)

Another option would be getting the average point of each cloud and using those for the crossover signals.

cloud2_avg = math.avg(htf_ma3, htf_ma4)
cloud3_avg = math.avg(htf_ma5, htf_ma6)

bull_signal = ta.crossover(cloud2_avg , cloud3_avg)
bear_signal = ta.crossunder(cloud2_avg, cloud3_avg)

lastly, to store the timeframe being used you can use the built-in timeframe.period

so:

res = timeframe.period
