  Hello, so i lost a trade on DAX today, in my IG.com app on my phone it says i lost -1615 NOK (norwegian kroner) but when i check in PRT that same trade is listed as -1720! Thats roughly 10€ difference / 10 pips if trading with 1€ contract, which i am..

  Is this… normal? Because once i noticed that, i see that basicly all my trades differ? Some more than others…

  Could it be the exchange rate that IG has? I believe it’s 0.5%. Don’t think PRT uses that.

  The difference isnt fixed either it seems, some trades are x different and some are y different. I guess my biggest worry is, what number is true?! Like should i trust the PRT numbers, which is my backtest numbers?? or should i trust IG numbers… if the difference can be 10!! pips, that would ruin a bunch of my systems i guess…

  The IG numbers are the numbers on which revenue is based / paid out?

  jebus89, you have probably already noticed that the spread that IG claims they have on their site is not the actual spread when trading live. It can be 5 times higher live. When trading manually on IG’s platform we see the spread when preparing an order but when using automatic trading with PRT we don’t know if the spread is fair or completely insane. This especially goes for indicies. Currencies is a bit safer. And it’s not actually IG’s fault, they are simply reflecting the futures market and the spreads go up in volatile markets.

  Hope you get an answer from them explaining the difference.

  Answer from IG (translated to english by me):

  “(…) The difference is that PRT does not use the Buy and Sell price. Instead PRT calculates your win/loss trade based upon the “open mid” and the current “mid price”

  The sums you see in your IG account is the correct sums. The sums on PRT are approximation/guess”

   

  (I think he means the “mid pric” =  average price between buy/sell price?)

  Ill include the original email in swedish at the bottom here incase i misunderstood something in my translation.

  I dont really know what to think about this.. if the backtest sums you see are approximation/guessing … you should really have a very good edge and you cant rely on systems with profit factor like 1.3 lol..

  Does everyone else know this already? Am i the last one to know, or does this stress more people then just me?

   

  original email:

  Skillnaden finns då PRT använder inte köp eller sälj priset. Istället beräknar PRT vinsten/förlusten med den öppna mid och den aktuella mid priserna.

  Förlusten du ser på IG plattformen är korrekt. PRT förlusten är endast en uppskattning.

  So are you talking about a live trade with real money on a live account? If so then PRT will send a BUY order to IG and IG will execute at mid price plus whatever half the spread is and then PRT send a SELL order and IG execute that at mid price minus whatever half the spread is. However those exact buy and sell prices are not sent to PRT so they have to use the midprice as they have no idea what the spread is.

  In back testing PRT know the mid price and we manually set the spread so back tests will calculate correctly – well sort of more correctly as we all know that spread these days is vary variable.

  I guess the answer is to ignore the PRT figures and only look at your IG account figures until the day that IG actually pass on important information such as actual buy and sell prices and the actual spread.

  I guess this also means that forward demo test results are inaccurate on the PRT platform for the same reason and if we look at our IG demo accounts then we have no idea which strategy did which trade. Now that is a bit annoying and worrying.

  Im talking about real account. And yes your summary would appear to be correct from what i can understand…

  I feel like my trust in the PRT platform has taken a hit today lol.

   

   

  Edit: im “fine” with ignoring the PRT sums, as you can just copy paste IG data to an excel file and study your actual numbers, but yes im worried that some of my Forex strategies, which some have a fairly low profit/loss ratio is not exactly what they seem to be from the backtest. Also how much am i loosing/winning because of this? I guess i have to copy paste IG numbers and then PRT numbers from all my trading and see what the difference really is.

  Sadly there is no way to do that with each individual strategy because IG cant seperate them in the history, like PRT can…..

  There was an issue with the Exitshort command not being recognised by IG, causing trades not to be exited at the right time, a guy posting his trading diary with IG got pretty annoyed and ceased trading, I asked if it was still an issue but never got a direct answer.
