Discrepancy on MarginRequired amount from API call and WebTrader

[SupereeDuperee 6]

I am trying to get Margin Required amount for GBP/JPY, 20000 Quantity. I call POST on this URL

https://ciapi.cityindex.com/TradingAPI/order/simulate/newtradeorder?UserName=demo210127&Session=

The Request JSON is

{
   "MarketId":401484385,
   "Currency":null,
   "AutoRollover":false,
   "Direction":"Buy",
   "Quantity":20000.0,
   "QuoteId":0,
   "PositionMethodId":1,
   "BidPrice":1.0001,
   "OfferPrice":999.9999,
   "AuditId":"1739236",
   "TradingAccountId":101295826,
   "IfDone":null,
   "Close":null,
   "Reference":null,
   "AllocationProfileId":0,
   "OrderReference":null,
   "Source":null,
   "PriceTolerance":0
}

 

The Response JSON is:-

{
    "Status": 1,
    "StatusReason": 1,
    "SimulatedCash": 49991.82,
    "ActualCash": 49991.82,
    "SimulatedTotalMarginRequirement": 2648.42,
    "ActualTotalMarginRequirement": 1280.36,
    "CurrencyId": 11,
    "Orders": [
        {
            "StatusReason": 1,
            "Status": 3
        }
    ]
}

 

From the documentation, if I am not wrong, "SimulatedTotalMarginRequirement": 2648.42, is the REQUIRED MARGIN Amount. I am using my DEMO account.

However if I try to place a NEW TRADE ORDER from the WebTrader website, using the same DEMO account I get required margin amount = 1369.10. Screenshot attached.

Why the margin requirement amount is not SAME from WebTrader and API call?

OK, Sigh of Relief! On LIVE account the Margin Required Amount API Call returns RIGHT Value = 1369.xx. So we should be good in real life scenario.
