I have read an explanation from one of the MT Russian guys on this, but it's easier for me to understand a Chinese dictionary than their writing. What's the difference between an "off quotes" and "requote" message on MT4? I know that the "requote" message asks the trader if he wants to deal at another price (quote), but I have been looking at the logs of one of our traders using a variable spread institutional feed through MT4 and I can't determine why sometimes he gets one message and sometimes another. Furthermore, if MT4 is a Fill or Kill system, why do these messages even come up at all? In other words, if the system price is outside of the deviation setting, why doesn't MT4 simply reject the order and leave the quote box up, rather than generate an "off quotes" message, force the trader to press "OK", then bring up the order entry box again and repeat all of this time consuming process? Is there a way to configure MT4 to allow manual traders to simply click and get either an instant execution or a rejection - AND then, if the trader gets a rejection, leave the order entry box up allowing the trader to continue clicking like mad until he gets executed? We are using an experimental multi-liquidity provider feed with a variable spread through MT4 (similar to CX). We cannot disclose anything until all our tests are done due to non-disclosure agreements. Can someone shed light on these things, please. Thank you.
