Naaah, This won't work here. There are too many different scenarios that can happen when your 'client' when using your 'Trading Automation software'. Also, 50% isn't attractable because there is other automated trading software that has the same purpose as your project that has an established name, reputation and also they don't deduct as high as 50% in the actual growth.
At least put some information about your software like making a website in it or put some code snippet in this thread.
What is the risk? have you even read what it says? Have you contacted the Manager? I think not. There is no risk. You pay 50% of the profit you earn. You don't have to pay anything! The software is currently in the last stage of testing and will be provided at the end of the video software, how it works!
This always has risk in it cause it involves money. There's a possibility that your trading software might fail in the process and make the user lose its money.
