Backtesting Error - Getting a different Currency MC

[LordTwig]

Hi,
I am doing some backtesting on my strategy, using EUR/JPY only.
Everthing is working fine until I get a margin call caused by USD/JPY.
Like opened trades price of EUR/JPY is at 123.00
Then get a margin call because price of USD/JPY is at 94.00 which equates to 29.00 (2900 pips)
This occurs a couple of times

Why is this USD/JPY even appearing?.....

I have nothing in strategy about currency types and in backtest market data only EUR/JPY is marked to use.

Backtest glitch?.....

Screenshots attached see highlighted row......

So here below you can see in the top left corner currency dropdown both EUR-JPY and USD-JPY are shown.
Also the history at the bottom shows both as well.
I don't know why the USD-JPY is shown as it is not selected in Market Data of strategy???

Without actual code, it is impossible to test, recreate this claim.
Can you post it here.

Unfortunately the code is Proprietry, not for public or other eyes

But, can you tell me if the dropdown and history should be displaying the USD/JPY if only the EUR/JPY has been selected in market data....

Btw....
If I use only GBP/JPY then dropdown and history has also GBP/USD in them
If I use only EUR/GBP then dropdown and history has also EUR/USD in them
Like....is this a cross rates thing....as it does not occur when only USD/XXX rates are selected

The account is in USD$....
TradeStation and Backtester Verion is :Ver 01.11.011212

Thanks

Hi LordTwig,

But, can you tell me if the dropdown and history should be displaying the USD/JPY if only the EUR/JPY has been selected in market data.... ?

Backtester uses USD/JPY automatically, because this instrument is required for P\L calculation to trade on EUR/JPY. It occurs if your account currency is not in trading currency pair.

LordTwig, could you please send me an excel file with history log.
