The One Leg<\/strong> edition is the entry-level version of the HFT Arbitrage Platform. It includes the one-leg latency arbitrage strategy \u2014 the simplest and fastest arbitrage execution mode \u2014 and all the core infrastructure needed to run it: reference feed connectors, broker bridge, execution engine, and basic risk controls.<\/p>\n One-leg arbitrage is the foundation of every HFT arbitrage strategy. The software monitors a fast reference price feed (NY5, TY3, LD4, cTrader Raw, or FIX), compares it to your broker’s quote in real time, and opens a position when the broker’s price is stale by more than your configured threshold. Execution happens in 0.3\u20131.2 ms on co-located VPS infrastructure.<\/p>\n This edition is best for:<\/p>\n If you need multiple strategies<\/strong> (hedge, 2-leg, 3-leg, triangular) or multiple concurrent brokers<\/strong>, see the [All Arbitrage bundle]<\/a> or the [Custom Configuration<\/a>]edition.<\/p>\n Latency arbitrage works only on brokers whose quote feeds lag the interbank price. It does not produce an edge on pure STP\/ECN brokers that pass orders directly to a Tier-1 liquidity provider. Most B-book brokers prohibit latency arbitrage in their Terms of Service \u2014 using this software against such brokers may result in profit clawback or account termination. Review the broker’s TOS before trading.<\/p>\n For a full explanation of how latency arbitrage works, which brokers support it, and what risks to plan for, see the [Latency Arbitrage Software \u2014 Complete Guide<\/a>].<\/p>\n The One Leg edition can be upgraded to the [All Arbitrage bundle<\/a>] at any time \u2014 the price difference is credited, and all your existing settings, broker connections, and strategy configurations carry over.<\/p>\n Related pages<\/p>\n – [Latency Arbitrage Software \u2014 Complete Guide<\/a>] One-leg arbitrage opens and closes a single directional position at the same broker, profiting from the broker’s price catching up to the reference. 2-legs arbitrage opens opposite positions across two brokers simultaneously, capturing the feed difference between them as market-neutral profit.<\/p>\n One-leg has higher expected per-trade profit but also higher detection risk; 2-legs has lower per-trade profit but lower directional risk.<\/p>\n<\/div>\n<\/details>\n One-leg latency arbitrage is restricted or prohibited by most major prop firms (FTMO, FundedNext, MyForexFunds). If you plan to trade on prop firm accounts, consider the All Arbitrage bundle<\/a>, which includes hedge and 3-leg strategies that are compatible with more prop firms.<\/p>\nWho this edition is for<\/h3>\n
