Error message

Indicator {indicator} is not supported. Please choose from: {list(best_ind_params.keys())}

What it means

Raised by get_stock_stats_indicators_window when the requested indicator name is not a key of best_ind_params (the fixed indicator dictionary: RSI, MACD, boll, etc.). The message interpolates {indicator} and the list of valid keys at raise time.

Solutions

1. Read the error message: it lists the supported indicators
2. Use one of the listed keys exactly (e.g. 'rsi', 'macd', 'boll')
3. Call get_stock_stats directly for custom indicators outside the curated set

Example fix

# before
report = get_stockstats_indicators_report('AAPL', 'CCI')
# after
report = get_stockstats_indicators_report('AAPL', 'rsi')

import tradingagents.dataflows.interface as iface
indicator = indicator.lower()
# whitelist derived from the module's best_ind_params keys
assert indicator in ('rsi','macd','boll','obv','mfi'), f'unsupported: {indicator}'
report = get_stockstats_indicators_report(symbol, indicator)

def is_supported_indicator(name: str) -> bool:
    return name.lower() in ('rsi','macd','boll','obv','mfi')

try:
    report = get_stockstats_indicators_report(symbol, indicator)
except ValueError as e:
    if 'not supported' in str(e):
        report = get_stockstats_indicators_report(symbol, 'rsi')  # default
    else:
        raise

When it happens

Trigger: Calling get_stockstats_indicators_report(symbol, indicator='cci') or a case variant like 'BOLL' — anything not exactly matching a key in best_ind_params in interface.py.

Common situations: Assuming any stockstats/pandas-ta indicator name works, case mismatches, or copy-pasting indicator names from other libraries.
