Minimum APR to keep a position open. Works together with Max Exit Spread.

Decision rules:
1. APR ≤ 0% → close immediately (losing money, spread ignored).
2. APR < Threshold → close only if spread is also below Max Exit Spread.
3. APR < Threshold but spread too high → hold + Telegram warning.
4. APR ≥ Threshold → hold (profitable, no action).

Example with Threshold = 50%:
APR at 80% → no action (above 50%)
APR at 30% + spread 0.05% → close (both conditions met)
APR at 30% + spread 0.25% → hold, wait for cheaper spread
APR at −10% → close immediately

Maximum spread allowed when closing a position. Works together with APR Threshold.

When APR drops below the threshold, the watcher checks this value before closing.
If the spread is cheap enough (below this value) → exits the position.
If the spread is too expensive → holds and sends a Telegram warning instead.

This prevents losing money on exit fees when it's better to wait.

Exception: If APR ≤ 0%, the position closes immediately regardless of spread (you're already losing money).

Example with Max Exit Spread = 0.10%:
APR low + spread at 0.06% → close (cheap exit)
APR low + spread at 0.20% → hold + Telegram alert

Minimum allowed distance to liquidation price for both Long and Short legs.
Each leg is evaluated independently.
If ONE leg fails, the guard triggers.
Conceptual formula:
Distance = |Current Price − Liquidation Price| / Current Price
Example:
Current price: 100
Long liquidation: 85 → 0.15
Short liquidation: 130 → 0.30
Minimum distance: 0.2
Long fails → guard triggers
