Hi Ton,

Try rounding the target price to the Symbol digits.

I get a "technical error" on placing a limit order, it only happens in LIFE mode not in backtesting

?

tradeOperation1 =  PlaceLimitOrderAsync(TradeType.Buy, Symbol, 1, symbol.Ask + symbol.PipSize, "", null, 1,  Server.Time.AddMilliseconds(100));

 

Someone any idea?

or: what is the closest way of sending a FOK order (Fill Or Kill) or (IOC fill available, cancel the rest)

Hi Panagiotis,
I'll try, but do you know of a better way to simulate FOK or IOC orders?

Hi Ton,

There is no way to simulate a FOK at the moment. All orders feature partial execution. IOC is available only for market orders so you can try a marker mrder with a market range.

Hi Panagiotis,

Isn't this the closest you can get to FOK (if it can't get filled it's cancelled isn't it)

PlaceStopOrder(TradeType.Buy, symbol, Vol, symbol.Bid, "o1", null,0);

Or is this one closer? (if it can't get filled it's cancelled agetr a few milliseconds. Isn't it)

PlaceStopLimitOrder(TradeType.Buy, symbol, Vol, symbol.Bid,0, Orderlabel,null,null,Server.Time.AddMilliseconds(ExpireMiliSeconds));

Hi Ton,

I just noticed that you set the expiry time 100 ms after the current time. That could be the source of the problem, since until is placed it might have already expired. 

Regarding "if it can't get filled it's cancelled isn't it" the answer is no, it will be filled partially and the rest cancelled. FOK means either filling it completely or killing it.

RE:

Hi Panagiotis

I'll test with a longer expiry time! good suggestion. But I thought accepting an order would not take more than 20ms or so + 20 ms for confirmation.

If that's the case Ill have to find a faster provider.  ;-)

What I also found is that Servertime (UTC+x) is not the time the order is arriving at the broker (UTC+y) !!
I sent expiration = Servertime 09:00 and get back from the broker its "10::00 here"???
Which server is "Server.Time" based on? at Spotware, at the broker, at .....?
 i'll test with DateTime.Now to see if that differs.

So what you say is that:

PlaceStopOrder(TradeType.Buy, symbol, Vol, symbol.Bid, "o1", null,0);

Is like an IOC order.

and:

PlaceStopOrder(TradeType.Buy, symbol, Vol, symbol.Bid, "o1", null,0,DateTime.Now.AddMilliseconds(200) );

Is as close to a FOK as you can get ( immediately. meaning within 200ms here)

Hi Ton,

Server.Time is the time of your broker's server based on the timezone you set for the cBot. 

Regarding the order types, both of the examples you posted are IOC orders. It means on triggering the order, fill whatever you can immediately and cancel the rest. On the other hand a FOK orders means fill the order immediately and completely or do not fill it at all. Since all orders in cTrader allow partial execution there is no way to satisfy the completely part of a FOK order.

RE: fill whatever you can immediately

Hi Panagiotis:

I love the responsiveness of CTDN!

you said:

fill whatever you can immediately 

That pops up the question:
{
   What is the use of an expirationtime then? (lagging Liq.Prov. maybe??) && 
   What is the definition of immidiately here? 
} ||
{
    Where in the documentation can I find a clear and exhaustive elaboration on these (for me important) issues?
}
 

Best rgds,
Ton

Hi Ton,

Immediatelly means on the existing liquidity. If the existing liquidity at the time of filling the order is not adequate to fill the order, then the order not filled is cancelled. It will not wait for new liquidity. Investopedia is a good resource for such definitions.
