  Anyone else have been noticing big differences this week between live and demo account? I run multiple systems exact same in demo as in live account and I know that sometimes there can be differ trades. Some trades might happen on demo that does not happen on live and some trades does not appear on backtest that appear on demo and vice versa. I know it can happen.

  But this week particular today it have happend more times than the last year. And also I got some wierd rejected orders I have never seen before.

  Is the a known issue this week or is this just me?

  What is the Rejection / Error message against your rejected Orders?

  I’ve had ‘shed loads’ of Stopped Systems this week.

  My strategies are 99% congruent live/demo/backtest… from my experience there are differences in:

  – limit/stop orders

  – entries without trigger (no “crosses over” but simply >)

  – no minimum distance for trailing and co

   

  … probably a lot more… but that is what was always wrong with me between live/demo/backtest.

  Well some of the sytems got stopped with “position does not exist” and also one with insufficient funds with a demo account with 100k euro trying to take a low pos size.

  But that is not the wierdest thing for this week. I have had MULTIPLE differnce entry trades on demo vs live. And the system closes it position exactly 1 minute after entry in demo (same system no trade on live). And when I backtest it, it is not there. I have multiple of thoose this week. And also I had system entries on demo but not on live. This has happend different systems and versions, which I run in live with SAME parameters and nothing happend on live.

  And as I mentioned I know there are differnces between live and demo and some trades can occur different. But also as I mentioned this happend more times today than for several years.

  This is one error I have got mutliple times to one system “This trading system had to be stopped because it tried to place an order which was rejected by the broker due to insufficient funds.” And I have funds for the system as I have a low position size compared to the capital avaliable. And I have ran this system for 4+ years and I have never seen this issue. And it is only happening in demo. I dont understand what has gone into PRT demo this week.

  Maybe someone at PRT is experimenting with solving the issue that in Papertrading-IB (which is a form of “Demo”) of the number of contracts not being respected. So they should multiply all with 1000 for Forex. But not so with IG because the contract is 100.000 by standard there (buy 1 piece, get 100.000). So if you recognize that all is multiplied by 1000 now, then you know what’s probably going on (remove one bug for the one environment and introduce it for the other).

  Of course this also eats your portfolio.

  Use GRAPH or GRAPHONPRICE to spot any incorrect calculation.

  On DAX it may happen to use + instead of – between two prices, high + low instead of high-low is a huge difference, from roughly 32K to 200 hundred!

  On EUR/USD it could be an incorrect multiplication or division.

  The Demo hasn’t worked for two days, do what you want.
  It blocks the algorithm immediately after 1 minute, otherwise it continues to open and close operations that do not exist in the Backtest, in some cases it exists in the backtest but does not perform any operations in the demo.
  It would seem that only the Nasdaq works.

  Luckily it’s just a problem with the demo, Live is Ok.
  IG should probably be contacted and warned

  It is getting quite annoying so it would be nice if a staff could inform PRT if they are not informed.
