Log Only Once "Warning: To meet brokerage precision requirements"

[AlexCatarino]

Expected Behavior

LEAN only logs the warning "To meet brokerage precision requirements". The text is generic: "Warning: To meet brokerage precision requirements, stop and limit prices are rounded down."

Same for "Warning: Due to brokerage limitations, orders will be rounded to the nearest lot size of"

Actual Behavior

We receive a warning for every order, and users are forced to round the prices manually, defeating the purpose of the rounding feature.

Potential Solution

Log once.
