Setting a starting stake each day

I  set a starting stake for each day's racing using eg.  stake=balance*0.05   and selecting one time only for execute.  I use progressive staking for the remainder of the day based on this starting stake.  Since I have used "One Time Only", I presume that on following day the starting stake will not change.  I know I can close the program and open again the next day or reload the trigger file, but is there any way of fully automating where I can keep the program running and have the starting stake change depending on the account balance?

Think I may have solved this:  found variable market_index. So I should be able to execute once per market on the first market of the day and use market_index = 1 as a condition.

If you start your trading session roughly at the same time of the day (say at around 08:00), you can change "one time only" to "no more often than 120 sec." and add the following condition:

Global Current Time is between 08:00 and 08:03

Thanks for that alternative suggestion Oxa, I found that my method works fine using market_index.  I now remember that I once requested  the market locator  Clear My Markets First to be implemented in the scheduled market search for this very reason.
