LimitEntry orders failing

I've noticed that many of the LimitEntry orders I request are not being filled.

The responses I get don't make much sense at all.

"...ORA-20143: Order price too far from market price :0.80063 vs 0.80073 "

Does the system seriously consider my order to be too far from the market price at 1 pip?

Here are a few other examples

0.96572 vs 0.96563
1.57025 vs 1.57072
0.96384 vs 0.96424
0.96384 vs 0.96424

Now, I'd really like to know what the system considers "too far" to be. It seems like it's different every time.

As I understand it LimitEntry orders should wait to be filled as per the documentation not rejected anyway.

I've also noticed that if I attempt to submit the orders again they are often accepted. There doesn't seem to be any logic to what's going on here.

Does anyone have any insight?
