X7 order_filled: AttributeError 'NoneType' object has no attribute 'split' — ft_order_tag unguarded (system_v3_2)

[Thug-angel]

Summary

NostalgiaForInfinityX7.order_filled() raises AttributeError: 'NoneType' object has no attribute 'split' whenever it is called for an order whose ft_order_tag is None. The system_v3_2 branch reads order.ft_order_tag and immediately calls .split() without the if order.ft_order_tag is not None: guard that is used everywhere else in the file.

Versions

• NFI: v17.4.281 (also reproduced on v17.4.268) — main HEAD at time of report.
• Freqtrade: 2026.5.1 (CCXT 4.5.55, Python 3.14)
• Mode: dry-run, spot, 5m timeframe

Offending code (v17.4.281, order_filled, system_v3_2 branch, ~lines 2696-2703)

if system_name_use == system_v3_2_name:
    filled_entries = trade.select_filled_orders(trade.entry_side)

    order_tag = order.ft_order_tag          # can be None
    order_mode = order_tag.split(" ", 1)    # AttributeError when None
    order_tags = []
    if len(order_mode) > 0:
        order_mode = order_mode[0]
    order_tags = order_tag.split(" ")       # same problem

Why this is a bug (internal inconsistency)

Every other ft_order_tag access in the same file is guarded, e.g.:

if order.ft_order_tag is not None:
    order_tag = order.ft_order_tag.partition(" ")[0]

There are 15 such guarded sites in v17.4.281 (e.g. lines ~1171, 41808, 41888, 44315, 44386, 46751, 46766, 48812, 65511, 65591, 68084, 68146, 70087, 70102, 72066). Only the order_filled / system_v3_2 branch omits the guard.

Impact

Non-fatal — the error is caught by strategy_wrapper, so the bot keeps trading. But order_filled aborts before it records the derisk_level_* custom_data, so derisk/grind bookkeeping is skipped for that fill. On a position that is being actively ground (a long-held DCA'd trade) it fires frequently — ~15-20 ERROR tracebacks/minute observed on one bot.

Reproduction

Occurs during grind/DCA fills on a long-held position where the filled order's ft_order_tag is None. Seen continuously on a spot trade open ~3 weeks (heavy grind).

Suggested fix

Guard like the rest of the file:

order_tag = order.ft_order_tag
if order_tag is None:
    return

or simply order_tag = order.ft_order_tag or "".

[iterativv]

Why the order is None, though. Let me check it.
