Automations

Counter trading

Answer outside buys and sells automatically, with an optional price defender.

Counter trading answers outside flow automatically: sell into outside buying, or buy into outside selling, with a share of the net flow each run.

Setting up counter trading: three strengths and the settings in plain words

Price defender

Optional. Sells harder above a ceiling (sell side) or buys harder below a floor (buy side). Set the bound as a USD price or a USD market cap, a multiplier, and a maximum per run. Bounds are in USD on every launchpad, including tokens paired with ETH, BNB or a stock.

Reactive mode

On venues where swaps are streamed live (such as Solana launchpads), counter trading reacts to each swap as it lands, with a reaction delay and a maximum per reaction instead of an interval. Swaps that arrive while a reaction is still running, and any amount above the maximum per reaction, carry into the next reaction, so heavy volume is countered in full rather than skipped.
