Its silly, but money is money. Especially when you locked in a big order on 1s. You constantly want to guide it down so you can fill.
I think if anyone has reservations, and good at cutting through the beaurocratic red tape, pick up the phone and contact LRS and ECOS yourself. Talk to exec. Management. Too many millennial traders looking for us Gen. Xers to hold their hands into a trade.
And if you're not spending money on researching companies before you buy large, you're doing it wrong. ECOS is solid, that's all I have to say. If anyone wants me to share more, hit me up on messenger so I can give you my PP email. Information is never free.
