Error message when trading manually with IB demo account

[mchiuminatto]

Hello

I'm testing a trading strategy before deploying to a customer, this is my first NT strategy and I'm getting errors I don't understand:




I have been able to reproduce the error fo manual trading when, from chart trader I click Buy Bid or Sell Ask, but never (so far) when I use Buy Market or Sell Market.

When this error is triggered by the strategy, the strategy is disabled.

Can you give me a hand with this?

I'm using real time and historic data from this Demo IBKR account.

Thanks in advanced.

Hello, thanks for writing in.

Before submitting the order with the saved price you will need to round it to the nearest tick size. We have a method that will do this for you here:

Please let me know if this does not resolve your inquiry.

Hi Chris

I still got the issue.


The problem, apparently, is when I'm submitting the stop loss and take profit orders:

Here is the log for one case:

The code I'm using to open the position is:

if (signal == Signal.LONG && this.BuyTrade)
{ // opens a long order
LastEntryOrder = EnterLong(this.PositionSize, _SignalId);
}
else if (signal == Signal.SHORT && this.SellTrade)
{ // opens a short order
LastEntryOrder = EnterShort(this.PositionSize, _SignalId);
}


To set take profit:

private void SetInitialTakeProfit(String SignalId, Signal SignalSide)
{
if (this.TpMode == TakeProfitMode.ON_DYNAMIC_TAKE_PROFIT)
{
double _tp = this.CalcTpAtMva(SignalSide);
LogEvent("Setting initial take profit for " + this.TpMode + " take profit mode at price " + _tp);
SetProfitTarget(CalculationMode.Price, Instrument.MasterInstrument.RoundToTickSize(_tp));
}
else if (this.TpMode == TakeProfitMode.ON_FIX_TAKE_PROFIT)
{
LogEvent("Setting initial take profit for " + this.TpMode + " take profit mode at " + this.TpFix + " pips away from opening price");
SetProfitTarget(CalculationMode.Pips, this.TpFix);
}
else
{
LogEvent("Setting initial take profit for " + this.TpMode + " take profit mode at " + this.TpSafe + " pips away from opening price");
SetProfitTarget(CalculationMode.Pips, this.TpSafe);
}

}


Where :

• TpFix and TpSafe are integers representing pips. Normal values are 20, 30, 40 to set the take profit distance in pips (20 pips, 30 pips, 40 pips repspectively.
• _tp is a price calculated as a function of an MVA and an offset in pips.

To set stop loss:

The code is:

SetStopLoss(_SignalId, CalculationMode.Pips, StopLossPips, false);

Where:

StopLossPips is an integer with values like 50, 100, 1000, representing the number of pips that the stop loss level needs to be away from opening price.


Is there any setting I cpuld be missing that is generating the issue?


The Setup:

IQFeed for real-time and historic
IBKR Demo account for trades.

Could be the difference between IQFeed and IBKR data the issue?


Thanks in advanced.

Adding more evidence



I can see that the rejected orders the price sent didn't ended in 0 or 5

The next image confirms that:




I think it is a rounding problem, but I'm applying the rounding method, what could be wrong?

Hello, thanks for your reply.

Please Print out the value of the Instrument.MasterInstrument.RoundToTickSize(_tp) variable to confirm the price value is properly formatted. Also, you are using values like this.TpFix and this.TpSafe, please make sure these are in a supported format as well.

Best regards,
-ChrisL

Hi Chris

For this order



The print outs of the take profit (raw and rounded)

3/17/2021 9:40:06 PM - Setting initial take profit for ON_DYNAMIC_TAKE_PROFIT take profit mode at price 0.725490000000001, rounded 0.72549

The code that calculates and prints:

double _tp = this.CalcTpAtMva(SignalSide);
double _round_tp = Instrument.MasterInstrument.RoundToTickSize(_tp);
LogEvent("Setting initial take profit for " + this.TpMode + " take profit mode at price " + _tp + ", rounded " + _round_tp);
SetProfitTarget(CalculationMode.Price, _round_tp);

Hello mchiuminatto, I found something you can do to fix this issue.

• Shut down NinjaTrader
• Make the adjustment below within Trader Workstation
  • File > Global Configuration
  • Display > Ticker Row
  • Enable 'Allow Forex trading in 1/10 pips'
  • OK
  • 
• Restart TWS and NinjaTrader

Please make this change and test the strategy again.

Best regards.

[mchiuminatto]

It worked Chris, thanks!!
