News trading and slippage: what a bot can and cannot do

News trading around CPI, NFP, and central-bank rates attracts bots because humans are slow. Brokers are not slow in the way marketers imply. During a release, spreads widen, books thin, and pending orders fill far from the price you drew. A news trading bot can stage rules before the print. It cannot force your broker to honor a fantasy fill.

Two honest modes

1. Straddle: place buy stop and sell stop a buffer away, cancel the other side if one fills, cancel both after a timeout.
2. Flatten and pause: close or block other expert advisors so a trend bot does not hold a position into a red-folder event.

The news trading bot is built for those calendar workflows, not for scraping breaking headlines.

Slippage is the product

If your backtest assumes mid-price fills at the second of NFP, throw it away. Test on demo during live events and record spread, slippage, and whether pendings were rejected. Caps on max spread should abort the straddle when the window is untradable.

Do not mix this with random Telegram “news”

A signal channel yelling “BUY GOLD NOW” during a spike is not the same as a scheduled calendar bot. If you copy those messages, use the Telegram copier with tight risk — and accept that many of those alerts are already late.

Suitability

News trading is a poor first bot. You need a broker that allows it, a VPS close enough to be irrelevant next to queue position, and capital that can absorb a stop blown by a gap. If that sentence is uncomfortable, skip this product.
