How to Oder Micro Lots in MetaTrader4 Expert Advisor?

I’m testing my strategy using Metatrader 4 Expert Advisor. I’ve tried demo account of both MIG Bank & Alpari (Aplari claims that they support micro lot), but i’m unable to order micro lots.

The below code works fine (using mini lot)
[B][I]OrderSend(Symbol(), OP_BUY,0.1, Ask, Slippage,0,Ask + TakeProfit, “My Coment” , 0, 0, Yellow); [/I][/B]

The Below code don’t work (using micro lot)
[B][I]OrderSend(Symbol(), OP_BUY, 0.01, Ask, Slippage,0,Ask + TakeProfit, “My Coment” , 0, 0, Yellow); [/I][/B]

Is it possible to open micro lot position in metatrader 4?

btw, is there any tweak that can make me order in units (not lots) ?

not really sure… MT4 may be hardwired so related adjustments can be limited and/or difficult
better check the MQL4 forum, you will be better served there

it depends on the limitations of your account. in this case the demo account. many brokers will not demo a micro or mini account. when you set up a demo you may have the option to chose that type of account you will demo. MT4 will not trade units, but a mini account with a $10,000 lot size and the ability to make trades at 0.01 lot is pretty small. Check out the specifics on account types on the brokers websites.
