GBP/JPY Trade is actually for real. I watched it closely through IB's Forex Feed, and eSignal FX GTIS Feed as well (IB's is always 3-4 Pips away, in your wrong direction, always!, but I will not get into that). Yeah, it's 23 Pips, but it really happened...
Please do! I'm using an IB feed with Ninja; mostly looking at EURUSD; so I didn't pay attention to other quotes. Is it just off compared with other feed or something to do with spread?
If you are using IB's actual feed, you should be fine. I am speaking of charting using other feeds, like eSignal's FX GTIS Feed. You will see a quote for, let's say an entry, but IB will not execute you until the price is like 3-4 Pips into it. Same thing with exiting trades. You think you made it according to eSignal, but IB did not execute. I do not know about other feeds.
You can try the free FXCM charting (data feed) software, for me it's the best for backtesting purposes. You can go back to any year you like (up to 20 years back) and test your trading ideas on the chart, from the 1 min to the monthly charts. I have spent years and years of testing with this wonderful and totally free charting software (it's called MarketScope).
A few traders (from ET and other trading websites) asked me to post more live Forex signals so next week I will start posting specific, real-time signals for a month or so. Until then, happy trading fellow FX traders (and traders in general of course).
