Solana Momentum Sniper settings

Every setting the Solana Momentum Sniper's Expert settings can change, with the same names and help the Strategy page shows. The path is the setting's name in the bot's config file, which is what Raw config and harkctl config show. "Starts at" is a new bot's value (the Balanced starter).

You rarely need these. The Simple controls set most of them for you: Style sets which tokens are eligible, the buy signal, the rug checks and the protect-gains band; Speed sets the priority fees and slippage; take profit and stop loss set the sell rules. Settings marked Advanced only appear only with the Advanced switch on.

Ranges

Protect gains on the way down and Take profit on the way up are lists of ranges. Each range has a start and an end, a step, and the share sold at each step:

a protect-gains range is measured as the drop from the trade's peak: within the range it sells a share for each step down, and everything once the drop passes the end;
a take-profit range is measured as profit: within the range it sells a share for each step up. A range whose start equals its end is a single sell at that profit, and it still sells if the price jumps past it.
