Simple Overnight Bot for MT5

I'm looking for a bot that just buys at market price at the end of the day, holds overnight and sells at opening the market at the next day. Just one trade at a time.

For preferences it might just have the following settings:
- opening time (in my case 9 AM CET for the DAX)
- closing time  (in my case 5:30 PM CET for the DAX)
- delay for opening time (e.g. 5 minutes after openening)
- delay for closing time (e.g. 5 minutes before closing)

It should have the option to set a fixed amount of money for every trade. And in addition the option to set a percentage of the account which should be invested for every trade.

I think that's it!
