How do I calculate 'diff to open' and set optimal trading parameters in the standard platform? - BJF Trading Group Inc

The ‘diff to open’ parameter should be set based on your broker’s spreads and the volatility of the trading symbol. A higher ‘diff to open’ value leads to fewer but potentially higher quality trade entries. There is no universal value: adjust according to your strategy and observed trade outcomes. If you need guidance for specific instruments, contact support with details of your broker and intended trading pairs.
