Arbiter Forex Arbitrage EA

Latency arbitrage involves taking advantage of slower quotes from one broker by predicting that they will eventually match the faster quotes from another broker. This allows traders to profit by anticipating market movements and placing trades in the right direction. These price differences may only last for a short time, but they can still be used to make substantial profits. The idea behind latency arbitrage is to exploit these delays in order to gain an advantage in the market.

  1. License Number - This is where you can enter your purchased license number to remove the restriction on only being able to trade on demo accounts.

The Expert Advisor has to be installed on two MetaTrader platforms - one acting as a server, the other as agent on the same local computer. The FAST broker (agent) sends price quotes from fast broker to the SLOW broker (server) from the predefined trading instrument. If price discrepancy occur between slow and fast broker, the EA attached on server will open position in the direction of fast broker's quotes.
  3. Server Port - The computer communication port used for data exchange between the agent and server. The chosen port must be unused by other software.
  4. Broker Color - The color of the price lines from FAST broker (agent) displayed on chart of theSLOW broker (server). Used for important initial price alignment between quotes of brokers.

  12. Manual Price Alignment (+/- points) - In SLOW broker (server) mode, if you disable auto price alignment, you need to manually match the prices between Agent and Server for the given instrument. It's important to do this correctly because it allows the EA to set the same starting point for prices between slow and fast brokers, which is needed to calculate price deviations and make trade decisions.equal starting point of prices between slow and fast broker in order to calculate price deviations and make trade decision.
  13. Gap Size (points) - In SLOW broker (server) mode this value is used to trigger the trade - if there is a gap between quotes of slow and fast broker more than selected amount in absolute points. During highly volatile sessions this value should be increased and vise-versa.

Example parameters of the Arbiter Forex Arbitrage EA

One important part of the setup process of the Arbiter Forex Arbitrage EA is the price alignment offset. Since the quotes of the slow broker always try to catch-up quotes of the fast broker, we have to initially align them (set the equal starting point). If quotes from the fast broker are not properly aligned with the quotes from slow broker, false trading signals may be generated, leading to losing trades. Keep an eye during the trading session on the EA and - if needed - adjust manually this offset.
