MT4: How can I set max lots per trade?

Hello

my question is simple I think

I wanted to enter a position with no leverage 0.15 lots, and by mistake I entered with 015 lots, means 15 lots (leverage * 100) and I didn't noticed it for an hour.
I was watching TV with a leverage 100:1 !

How can I edit my MT4 so not to be able to enter a position higher that 2 or 3 lots? SO if I enter again by mistake more lots, MT4 to reject the order.

Without an EA on a chart actively denying you to trade, it is not possible i think.

Metatrader dont have limitations built in.

An EA checking lot size against a global set max value might work (just a thought, haven't tried it)

Maybe you can ask your broker to set lot size limit for your account, this may work. Or you can open trades with scripts instead using "open order" window

Tools/options/trade tab/ size by default/ click default box and set to your lots.

This will NOT stop you changing the default value if you are that careless!

The other option as mentioned by others is to use an EA or script.
