demo vs live

I decided to run a test on IBFX, I was thinking about if a demo account has the same variables , not sure if that the correct term, as a live account, ie. data transfer speed, I was curious if a demo account was taken with the same seriousness as a live acount by the broker...

I only started this last nite, I placed an EA on a live account and the same EA on a demo. expecting the results to be close to the same, but they are not. so far the demo account has different entry point prices, much different trade results. the demo initiated a usd/jpy trade that the live account didnt, whick Im glad, because it was a losing trade..

the demo is sitting at + 12 pips and the live is at +55

One factor is demo backtest does not have Time variable.

Demo starts on GMT0000 on the date you select, but live account starts trading on the time you activate your EA.

theres no backtesting involved.... just 2 accounts running at the same time with an EA

I have done some reading on this and have found out its a common occurance.

Ya, you're correct. If you did notice some EA performance slowly, you will even notice a weird case. Whereby the EA taken a trade at a unachievable price.

Example :
GU high 1.9900 low 1.9800

But the EA open a trade at price of 1.9915. How could it happen? But it does happen in demo account, but nvr occurs once in live account.
Guess the price feed is a bit different for both...

Juz my guess,

i always hear people complain that their trades are deleted in their live accounts.. but i was running a EA for testing in a DEMO account, a trade was deleted.. i saw it open and my chart shows that i have open a position but the history doesn't show anything.. and it was positive.. what is the point of deleting a position in a demo? The EA is not even earning my demo account is down $500 and would still be down even with that positive position..

Anyone know why this happen?

i guess they have something in common after all..

That could happen if the spread suddendly changed.
The change is not an actual price the pair reaches but the spread increase trigger the execution of a pending order.

Let me tell you what I saw - very surprising to me. Please let me know if someone else has experienced something like that.
I have 2 computers one is running a demo account and the other live. When I run backtest on the PC which has a demo account my EA can place orders with micro lots - 0.01 and mini 0.1. On the PC with the live account my backtest only runs if I use mini lots - 0.1 If I try to use micro I get OrderSend Error. I am wandering whether it could be because the live account is actually still not funded - but why is this affecting the backtesting. Also I believe many providers do not update their demo server's with actual swap - in this particular case when I saw it the demo had higher swap than the live - may be forgotten for a reason
