Post-only quotes on both sides of one market: SNDK on Entropy, or BTC on TxFlow. Every fill is volume. Set a margin, a leverage and a stop loss; the session runs on our servers until you stop it or the stop loss is reached, and closing this tab does not stop it. Nothing on a second venue cancels the price, so what it holds moves with the market.
Darkside trades without a hedge. A session can lose more than it saves on fees, so put in only what you can lose. Results above are what the venues reported; open interest and depth limits still apply.
