Check startup history for recursive indicator convergence

Goal

Goal: Compare EMA-like values across startup lengths to find early signal drift.

Steps

1. List recursive indicators and startup_candle_count. [recursive]
2. Run freqtrade recursive-analysis --strategy MyStrategy --pairs BTC/USDT. [recursive]
3. Choose a stable warmup from delta results and rerun the backtest. [recursive]

How to verify

Key recursive indicators converge within tolerance at the selected startup length.

Troubleshooting

Fetch earlier candles and inspect indicator logic when data/deltas are bad; do not mask with arbitrary constants.
