//| Write every Market Watch symbol's contract and SWAP specification |
//| to Common\Files\Warrior_EA\symbol_specs.csv, for the research     |
//| cost model. Read-only: no orders, no chart changes.               |
//|                                                                   |
//| Swap is the reason this exists. Bar history carries no swap, and  |
//| the research policy is to charge the CURRENT swap, negative on    |
//| both sides, every night, with the 3-day rollover applied. Whether |
//| SYMBOL_SWAP_LONG/SHORT is the per-night figure or already the     |
//| tripled one is NOT answered by the API; this dump records what    |
//| the spec says together with SYMBOL_SWAP_ROLLOVER3DAYS so the      |
//| research side can compare it against a real deal's DEAL_SWAP.     |
