Pump and dump

Pump and dump - A manipulative tactic (often unethical) to inflate and then crash an asset’s price. In slang, a pump and dump is when manipulators hype an asset to “pump” the price up, then sell into the frenzy and let it crash. In a Forex-bot context, this might refer to a rigged scheme or a short-lived algorithmic spike. Such activity is essentially fraud: unscrupulous bots or traders hype the market, then dump positions. Example: “That sudden rally looked like a pump-and-dump; the bot farm collectively sold into the spike and the price plummeted.”
