Is anyone else experiencing this MT4 issue?

A user reported a problem with his EA on the mql4 Forum, his EA was running on a EURUSD chart and he was using Bid price to place an order on EURUSD and USDCHF. He explained that it worked on one of his PCs but not the other . . .

It was explained to him that Bid was relative to the chart that the EA was running on so it could not possibly place the order on USDCHF at Bid from a EURUSD chart . . . well it seems that it can.

Try the attached EA on DEMO account on a GBPUSD chart, if your symbol names for EURUSD and USDCHF differ please change them in the EA's Properties>Inputs , leave the Open Price at something daft, like 10,000 or 0.1 or 15, etc . . .

It will only place trades if there are no current trades open . . .


2013.03.20 12:08:39TestBuySell GBPUSD,H1: Buy Order opened, requested price 10000 opened at 1.294 current EURUSD Ask is 1.29397
2013.03.20 12:08:39TestBuySell GBPUSD,H1: open #48266520 buy 0.10 EURUSD at 1.29397 ok

2013.03.20 12:08:38TestBuySell GBPUSD,H1: Sell Order opened, requested price 10000 opened at 0.9447 current USDCHF Bid is 0.94469
2013.03.20 12:08:38TestBuySell GBPUSD,H1: open #48266519 sell 0.10 USDCHF at 0.94466 ok

this is what I get written to my log with the EA on GBPUSD, you can see it placed trades on EURUSD and USDCHF their current Bid/Ask prices and not at the price I requested.


Please let me know what you find.

Thanks

hey raptor..... did not need to try your ea...... my experience is limited to ibfx...... when using ordersend OP_BUY or OP_SELL ibfx places the order at market..... so if the orders original entry price is off it does not matter.... the order will go in at the current correct market price...... and it will go in whether or not there are existing orders.....

i believe they do this for faster execution and no requotes.....h

Thanks for the reply, do you know how long they have been doing this for ? doesn't this also mean that we no longer have any say in what slippage we are willing to accept ?

not sure of exactly how long, seems like maybe for less than 2 years now.... correct, there is no longer slippage with ibfx..... we just use 0 as a place holder.....h

Thanks for that, pity Metaquotes didn't update the documentation to reflect this.

forgot to mention and this is very very important, ibfx only corrects the ordersend() line.....

we usually immediately follow up with a ordermodify() line to set profittargets and stoplosses..... extreme care must be taken..... ibfx will not correct incorrect marketinfo() type values here.....

this gives rise to the possibility incorrect stoploss's and profittargets......h

@RaptorUK,
I just tested your test-EA on FXPRO demo platform.
There is no problem.

2013.03.20 15:06:49 TestBuySell GBPUSD,H1: Buy Order Open failed.EURUSD Error: 129
2013.03.20 15:06:49 TestBuySell GBPUSD,H1: Sell Order Open failed on USDCHF Error: 129

It didnīt open orders.

Seems to be a broker related problem, not caused by Mt4.

ERR_INVALID_PRICE 129 Invalid price.

Big problem , there should be Error 129 but the beast just opened both orders.
Not good.

Yep, I'm aware of how to send an Order to an ECN type Broker, by incorrect MarketInfo() type values do you mean if I calculate my SL & TP based on the wrong symbol's Ask/Bid price ?

Glad you are able to reproduce what I am seeing, I'll be talking to Metaquotes about this, the least they can do is update their Documentation.
