Icoa Inc (ICOA)

[Jayman5000]

Different brokers operate differently.

That's it. That's all. There is no secret conspiracy you have stumbled upon where certain MM's are trying to keep the price of ICOA down.

They just don't want you to enter an order with a price way out of whack, it's a safety feature meant to protect dumbasses that enter orders with a decimal point out of place, for example.

Not all brokers do it but some do.
