Order price did not pass validation - error

[cjdsellers]

Hi guys,

I've been testing some automated strategies on an FXCM demo.

for instruments AUS200 and JPN225 I continually get this error when it attempts to enter a position with a StopMarket order; 'Order price did not pass validation'.

- What are the requirements for a price validation?

Of note, I code very carefully. I'm rounding to tick size so that the price is legit, I'm also checking the current Bid/Ask as applicable and making sure I'm not attempting to place StopMarket orders inside the market (its always beyond a bar which has already closed and thus formed a high or low (as applicable) away from the market, plus I add a volatility buffer too...)

Also of note, my strategy is working on four currencies, USOIL, XAUUSD, GER30 and SPX500... I find it odd that NT is only throwing this error for AUS200 and JPN225.

Thanks in advance.

Hi Patrick,

I may have saved you the trouble, I reviewed the log and traces myself and found the following at the rejection point;

"2016-03-30 02:41:28:067 (FXCM D27441205001) Fxcm.Adapter.onRequestFailed: sRequestId='A10D1_2EFD732269EB3CA5E053D5293C0A336F _03282016073219728409_QRQA-64152' sError='Description=19915;DAS 19915: ZDas Exception

of particular interest I actually found the FXCM API error code;

"Error='Description=19915;DAS 19915: ZDas Exception
ORA-20105: Order price did not pass validation."

upon searching Google I found this write up about it;

6. Why did I get the following error message: 19915: ZDas Exception ORA-20105: Order price did not pass validation 8=FIX.4.4|9=179|35=D|1=2620231783|11=FXSTAT_329514 21147085|15=EUR|38=5|40=3|54=2|55=ESP35|59=1|60=20 150113-11:04:45|99=9864|386=1|336=FXCM|625=EUREAL|516=0|5 26=OT_-2_1421147086_ESP35_ESP35_0__0_|10=080

"Unordered List ItemThe rejected orders error message is generated when the stop price is within 12 points of ask price. The reason for rejected orders is because the Minimum Stop Distance for ESP35 is 12 points. For example, if the Ask price was 9911 and your Stop price 99=9917, you would receive this error message. In this example, the stop price should be at least 9911 + 12 = 9923."

Which leaves me one question now, how can I determine the Minimum Stop Distance for an instrument?

Also does NinjaTrader have an object I can call to determine this automatically?

I've checked Instrument. and Instrument.MasterInstrument and can't see anything obvious there.

cheers,
Chris

Hello cjdsellers,

Thank you for your response.

There are no items we could pull to know the minimum distance or maximum distance needed. The strategy would need to figure this in it's calculation - meaning you would need to implement logic for this. You may need to create another strategy or use different parameters for different instruments.
