How to add all or some conditions to alert ? - Pine script tradingview

Question

I have a list of conditions for a candle. This is just an example:

aa = (close > open) and (low > low[1])
bb = (close[1] > open[1]) and (close[1] > 5)
cc = (close > ((high[1] - low[1])*23.6/100 + low[1]))
dd = (close > EMA34) and (close > ema(close, 10))

I set alert using the following code:

if aa
    alert("A- " + tostring(close, "#.######"), alert.freq_once_per_bar)
else if bb
    alert("B- " + tostring(close, "#.######"), alert.freq_once_per_bar)
else if cc
    alert("C- " + tostring(close, "#.######"), alert.freq_once_per_bar)
else if dd
    alert("D- " + tostring(close, "#.######"), alert.freq_once_per_bar)

With each condition, I will get an alert with a letter at the beginning of the message so I can know the priority of the conditions, ie A is the best, D is the last one.

I would like to know if there is any way to check all conditions at the same time, so I can set the priority like:

• if the alert has all conditions fulfilled, so it's the best A
• if the alert has at least 3 conditions fulfilled, then it's B
• if the alert has at least 2 conditions, then it's C
• and if there is only 1 condition fulfilled, then it will be D

The real list has more than 10 conditions so I cannot check them manually. Please give me some code to do it programmatically.

I think, it's something related to array but I don't know how to do it.

Thank you for helping me.

Answer 1

aa = (close > open) and (low > low[1]) ?1:0
bb = (close[1] > open[1]) and (close[1] > 5) ?1:0
cc = (close > ((high[1] - low[1])*23.6/100 + low[1])) ?1:0
dd = (close > EMA34) and (close > ema(close, 10)) ?1:0
number_of_condition_true=aa+bb+cc+dd
bool all_condition_true=na
bool three_condition_true=na
bool two_condition_true=na
bool one_condition_true=na
bool none_condition_true=na

if number_of_condition_true>=4
   all_condition_true:=true
else if number_of_condition_true>=3
   three_condition_true:=true
else if number_of_condition_true>=2
   two_condition_true:=true
else if number_of_condition_true>=1
   one_condition_true:=true
else if number_of_condition_true==0
   none_condition_true:=true

this is one of the ways ,this code will help you in programming your logic. in the above code i have replaced it into numerical value if true , than i have added all , this will give you the overall how may are true at a time.
