hi,

i am sending bid/offer orders with > 1 second expiration time. i keep getting this error:

Order PLACE BID 1000 EUR/NZD @ 1.78557 EXPIRES:2018-10-10 21:39:33.650 GMT is sent at 2018-10-10 21:39:32.474 GMT by the strategy "StratFeed": from the local computer
Your order has been rejected due to validation failure. incorrect expiration time

notice that i get the rejection message BEFORE my order is due to expire.

Hello,

There much depends on how your strategy calculates goodTillTime parameter. It is just hardcoded to 1000ms, or some function? Provide some code sample, which produces this error.

thank you very much for the quick reply! my code has a dynamic goodTillTime but i have a minimum set to 1000ms. it essentially looks like this:

if (gft >= 1000) {
   engine.submitOrder(getLabel(), inst, OrderCommand.PLACE_BID, getamount(), getPrice(), 0, 0, 0, System.currentTimeMillis() + gft);
}

what i don't understand is how the server rejects my order before it is set to expire. the JForex logs show correct timestamps (i.e. in the future) every time. also, this doesn't ALWAYS happen -- just about 50% of the time.

I suppose this may happen because time on client does not exactly match time on server. '1 sec' is rather short period, for example if your local time is 0.5+ sec ahead of server time - then you get few milliseconds left for network traffic of variable latency, what depends on how far you physically away from dukas' servers ...
