Every latency arbitrage trade starts with the same bet: the fast feed has already moved, and the trading account’s price is about to follow. Most of the time that is exactly what happens. But sometimes the fast feed turns around while your position is still open. When that happens, the trading account’s price is about to follow the fast feed again, this time against<\/em> you, and the only question is how much of that move you sit through before something closes the trade.<\/p>\n\n

Until now the answer was: whatever your S\/L, T\/P, trailing stop or Order Lifetime decided. Reverse signal diff<\/strong> is a new per-instrument parameter in the HFT Arbitrage Platform that adds one more exit. It closes the position the moment the fast feed signals the opposite direction, before the trading account’s price catches up. This guide explains how it works, which strategies support it, how to pick a value and how to read it in the log.<\/p>\n\n

The problem: an exit that waits too long<\/h2>\n\n

A latency arbitrage entry is based on a difference<\/em>: the fast feed leads the trading account by more than your Diff to open<\/strong>. A Buy opens because the fast feed is above the account’s price; a Sell opens because it is below. The strategy then manages the position with its hidden S\/L and T\/P, a trailing stop and Order Lifetime.<\/p>\n\n

Those exits all look at what the trading account’s price has already done. None of them reacts to what the fast feed is doing now<\/em>. If the fast feed drops sharply a few seconds after your Buy opened, the strategy already has the information that the account’s price is about to fall. A classic stop still waits for that fall to happen and then closes the trade at the worse price. Reverse signal diff closes it on the quote where the reversal first shows up.<\/p>\n\n\n

The Buy opens when the fast feed leads the account up by more than Diff to open. When the fast feed turns down and the Sell difference passes Reverse signal diff, the Buy closes on that quote, before the account price follows the fast feed down.<\/figcaption>\n<\/figure>\n\n\n

What Reverse signal diff is<\/h2>\n\n\n\n
Where<\/strong><\/td>The instruments table, one value per instrument. In Latency<\/strong> the column sits right after Diff to open<\/strong>; in the 2 Legs Latency<\/strong> strategies, right after Diff to open 2<\/strong>.<\/td><\/tr>\n
Value<\/strong><\/td>0 or empty turns it off. This is the default, so instruments you already have keep trading exactly as before.<\/td><\/tr>\n

How it works, step by step<\/h2>\n\n
    \n
  1. The same measurement as for entries.<\/strong> On every price update from the fast feed, the strategy measures the difference between the fast feed and the trading account, exactly as it does when it looks for entries. These are the numbers you already see in the Curr Buy Diff<\/strong> and Curr Sell Diff<\/strong> columns (Curr Diff 1<\/strong> and Curr Diff 2<\/strong>, shown as Buy\/Sell, in the 2 Legs Latency strategies).<\/li>\n
  2. The opposite direction.<\/strong> For each open position it reads the difference in the opposite direction: the Sell difference for a Buy position, the Buy difference for a Sell position. With Reverse trading<\/strong> on, the directions swap, matching how the position was opened.<\/li>\n
  3. Close on that quote.<\/strong> If that difference is greater than Reverse signal diff, the position is closed on that same quote. It does not wait for S\/L, T\/P, the trailing stop or Order Lifetime.<\/li>\n
  4. A normal close.<\/strong> The close is done exactly the way the strategy closes a position when its hidden S\/L or T\/P is hit, so locking, virtual positions and the trade history all behave as usual.<\/li>\n<\/ol>\n\n\n

    Reverse signal diff is checked on every fast-feed update, alongside the exits you already use. It never replaces them.<\/figcaption>\n<\/figure>\n\n\n

    A worked example: Latency on EURUSD<\/h3>\n\n

    Diff to open<\/strong> is 3 and Reverse signal diff<\/strong> is 2, both in points.<\/p>\n\n
