Re: [amibroker] ib controller 1.2.0 truncate price to 2 decimal places only, AmiBroker Email List Archive

thanks a lot.
btw, I have a conceptual question on applying trailing stop using the function applystop.

if I apply trailing stop before proceeding to my logic for doing realtime trade,
ApplyStop(stopTypeTrailing, 2, 10, 2, True );

for 10% trailing profit stopping.

then I have another function to work on the Buy, Sell, Cover, Short and determine how to place the ibc.placeorder function.

are those parameters actually changed by the applystop function so that I don't have to rest of the code? Thanks.

Rgds,
Jacky

No it does not truncate anything. It rounds to user-specified TickSize.

You really need to READ the documentation

http://www.amibroker.com/at/

It clearly says:

PlaceOrder( string Ticker, string Action, number Quantity, string Type, number LimitPrice, number StopPrice, string TimeInForce, bool Transmit, [optional] number TickSize = 100, [optional] string Attributes = "", [optional] string ParentID = "", [optional] string OCAGroup, [optional] number OCAType, [optional] string FAParams)

TickSize - defines minimum price fluctuation allowed for given symbol expressed in pips (= 0.0001). For most US stocks it is 100 (represents 0.01 move), for most currencies: 1 (represents 0.0001 move), if minimum move is less than 0.0001 you can use fractional values for example 1/100 for 0.000001 move.

Subject: [amibroker] ib controller 1.2.0 truncate price to 2 decimal places only

Hi All,
I found that the IB controller truncate the price I supplied to only 2 digital. For most stock, it's ok, but when I trade forex, this is a big problem, e.g. EurUSd 1.415 become 1.42. Any one can help?
