Does anyone know which broker has no limit on the number of open orders and no maximum lot size?

I don't think that there is one without such a limit.

As I wrote above I don't know of such a broker.

 
I see many broker set lot limit and order limit, why does it decide ?
 
  1. Hon Yin Shum: why does it decide ?

    Because it is their business.

    Never risk more than a small percentage of your account, certainly less than 2% per trade, 6% total to the account. Risk depends on your initial stop loss, lot size, and the value of the pair. It does not depend on margin and leverage. No SL means you have infinite risk.
    1. You place the stop where it needs to be — where the reason for the trade is no longer valid. E.g. trading a support bounce the stop goes below the support.
    2. AccountBalance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the spread, and DeltaPerLot is usually around $10/pip but it takes account of the exchange rates of the pair vs. your account currency.)
    3. Do NOT use TickValue by itself - DeltaPerLot and verify that MODE_TICKVALUE is returning a value in your deposit currency, as promised by the documentation, or whether it is returning a value in the instrument's base currency.

    4. You must normalize lots properly and check against min and max.
    5. You must also check FreeMargin to avoid stop out

    Most pairs are worth about $10 per PIP. A $5 risk with a (very small) 5 PIP SL is $5/$10/5 or 0.1 Lots maximum.
