Please help me. What is wrong with my order? I cannot execute it.
If you look at the journal entries, it indicates the order rejection occurred due to 'Off-Quote'. This indicates that by the time the order reached the system for execution, the current market price was outside the maximum deviation you specified for the order. The order will be rejected in this case. This can be caused if there is any latency in the internet connecting causing the order to arrive after the market price has changed or if you are sending orders during volatile market conditions when prices are changing rapidly. Not allowing any flexibility would increase the likelihood that the price has changed by the time your order arrives.
What you can do is increase the maximum deviation setting to 10 or 20 which would give you 1.0 - 2.0 pips of flexibility for market movement rather than having the order being rejected outright.
The default maximum deviation setting can be changed by navigating in MT4 to:
Tools -> Options -> Trade [TAB]
Set Deviation by default to XX pips.
