program to send notification for CRYPTOCURNCY price. with special trading algorithm

I need a program that receives price and volume data from the "data provider" for the cryptocurrency And send "notifications" based on a trading system at specific times. The required task that a freelancer must perform is simple. He should know the knowledge of working with "data providers" and good programming knowledge. There are no restrictions on the programming language. Python will be a good choice for this. Please also note that after the delivery of the application, there are minor adjustments and small changes to the application (especially for the alarm limit) that should be included in the price of the work. I pay the monthly "data provider" fee. There are 3 main systems in the trading system which are based on volume and slope of the price charts. Details will be discussed in the chat
