Hi Experts,

I am absolute new to pine editor, so I would like if someone with knowledge can help me with a script which I need to enable me to create multiple alerts with one script

Points Which needs to be covered. Alert should pop up when
1. 50 EMA crosses 200 EMA (both side - up or down)
2. In multiple time frame ( 1 or 3 or 5 minute)
3. For multiple stocks (Eg: banknifty, Nifty, Mindtree, etc)

I have updated the script to get the 50 & 200 EMA, but I need help in script for setting alerts and also the time frame

I would really appreciate if some one could help me with a pine script for me to work around to create this alert in trading view.

Thanks,
Tejas

//@version=5
indicator(title='50-200new', overlay=true)

i_T1 = input.symbol('BANKNIFTY')
i_T2 = input.symbol('NIFTY')
i_T3 = input.symbol('MINDTREE')

f_strategy() =>
emafast = ta.ema(close, 50)
emaslow = ta.ema(close, 200)


//get user input
emalength1 = input(title='EMA 1 length', defval=50)
emalength2 = input(title='EMA 2 length', defval=200)

//get EMAs
ema1 = ta.ema(close, emalength1)
ema2 = ta.ema(close, emalength2)

//Plot EMA
plot(ema1, color=color.new(color.green, 0))
plot(ema2, color=color.new(color.black, 0))

//Send our alert if there is a golden crossover

Here's something similar that you should be able to customise.
