Optimizing in the background while running live or backtesting

[paisan]

I have tried a few different ways, but they have all run into a wall. Is this possible in some way?

When running a backtest I would like to have an optimizer run when a trade ends or at a certain time, let's say every 30 minutes.

I did not mess with the regular runstrategy() that starts the strategy. I made a new optimize_strategy() that has the optstrategy that I try to run while the regular backtesting is on, but when I start it I get this:

AssertionError: daemonic processes are not allowed to have children

I made a sleep() test to see if the problem came from the initial runstrategy()

def optimize_strategy():
    print('Before sleep')
    time.sleep(10)
    print('After sleep')

when started from notify_trade() it pauses like it should

    def notify_trade(self, trade):
        if trade.isclosed:
            optimize_strategy()

So, what I would like is the following:

1. In backtesting, run a separate optstrategy when I choose and have the regular code pause when it runs.
2. In live, run a separate optstrategy in the background when I choose and without interrupting the regular code.

Is it possible?
