mobile trading app that allows technical alert set up

 
hi 

does any one know any android mobile trading app (either from broker or platform), that allows technical alert to be set up, from the mobile end?

for example, i can set an alert from a list of technical indicator, than choose > = <, than choose from a list of indicator again, and set trigger when condition meet or candle end, of coz i can choose different time frame

from technical point of view, i dun see how difficult it is to implement this function, a lot of mobile trading app (including mt4 and mt5) can show u the technical indicator already, they just have to create the function, and the user put the ingredient (price or technical indicator value) into the formula, it produce a notification when condition meets.
