Using microlots in EA

[[Deleted]]

double minLot = MarketInfo(Symbol(), MODE_MINLOT);

How do i define a microlot?

[[Deleted]]

IF u Print("MODE_MINLOT=",MarketInfo(Symbol(), MODE_MINLOT));

u will most likely see:

IF ur broker support microlots

THEN MODE_MINLOT=0.01 //1microlot is 0.01 decimal

ELSE MODE_MINLOT=0.1 //1minilot is 0.1 decimal, and broker support minimum lot size of minilot

.

look also at Print("MODE_LOTSTEP=",MarketInfo(Symbol(), MODE_LOTSTEP));

which afaik always same as MODE_MINLOT

why? u can only have multiples/units of MODE_LOTSTEP 'lots' in Trade Order, else get nice system error code back... ;)

.

anyway, some ideas maybe 4 u

Microlot is smaller than Minilot.

For FX:

LOTSIZE = 100000 = "standard" lots base size

LOTSIZE = 10000 = "mini" lots base size

MINLOT is the smallest fraction of LOTSIZE for a new trade you can open.

LOTSTEP is the increment for closing/reducing a position.

Microlot is ability to open less than 0.1 of standard or less than 1.0 of mini

I have seen 0.5 as minimum lot with 0.1 as LOSTSTEP at one Dealer.
