How should one warm up data for indicators while in live trading?

My strategy needs some data before it can run in live trading, otherwise , I have to wait for 1 months, what is the correct way to do ? the strategy must be work both in backtest and live trading.

@videni In live trading you normally warm up your indicators the same way you do in backtesting: by loading historical data before the strategy starts processing live ticks. Most trading engines (including Nautilus Trader) allow you to bootstrap or preload a lookback window of bars so that all indicators have the required number of observations before the first live event arrives. This avoids waiting days or months until enough bars accumulate.
