Interactive input strategy

[robomotic]

Hello there,
I have just started to learn bt which is awesome.
I was just reading the documentation and examples, however I cannot find anything relating to using input to control a strategy.
What I usually do when I deploy a trading bot is to monitor it and if something is going to be wrong make a few adjustments via keyboard commands in real time.
Is this possible with bt?

Cheers.

No such thing is implemented. That's a huge use case. For starters some quick questions:

• Which commands?
• You are resampling live data to 15 seconds and you spend 31 seconds in the interactive mode, should the strategy skip the 2 15-seconds bars from the resampler? See them later and what happens if any of them generates a signal for trading?

A possible approach:

• Create a thread during the initialization of your strategy and use a method of the strategy as the target
• This method, now running in parallel (as much as allowed by the GIL) can implement keyboard processing

is it possible to create a strategy like this one to get the period outside of strategy?

class secondstrategy(bt.Strategy):

  def __init__(self, period):
    self.period = period
    self.rsi = bt.indicators.RSI_SMA(self.data.close, period=self.period)

  def next(self):
    if not self.position:
      if self.rsi < 30:
        self.buy()

    else:
      if self.rsi > 70:
        self.sell()
