response from alpari uk:
Re-quotes occur as a result of rapid changes in market prices, combined with maximum deviation being set too low, or even at zero. If the maximum deviation is set to zero, it means that the platform will only execute at the exact price on display at that time. This can be unrealistic in a fast-moving market when the price is constantly changing.
In order to minimize the possibility of Re-quotes, you may wish to tick the “Enable maximum deviation from quoted price” box, and set it to 10 pips as follows:
This means that your order will be done, up to 10 pips either side of the price shown. In the scenario above, the highest price at which you will buy is 1.40658, and the lowest price at which you will sell is 1.40622. This will greatly reduce the possibility of Re-quotes.
I hope this helps, but please do not hesitate to contact us if you require further information.

ok so the question is can we or should we use max deviation, and can this be achieved with the TMT/FMT ea.
