LOT filters for spot market order

Hello friends. I have read quite a few things about all the filters, including a good number of this forum’s topics, but I got a little confused about LOT filters, regarding to spot market orders.
Before placing an order, should I verify both LOT_SIZE and MARKET_LOT_SIZE or for spot market orders I should handle just the latter?
Thanks!

You should verify for MARKET_LOT_SIZE if you are making a market order. Otherwise, you should verify for LOT_SIZE before placing an order.
