Hopefully someone experienced could answer this question on Forex trading. Have recently started trading CFD's. I got stopped out on a short position. However, the 5 minute timeframe broker supplied chart (AUD/GBP) did not match the Trading View 5 minute chart. It was out by about 5 to 6 pips. I am not talking about the spread but the ACTUAL PRICE traded on both charts did not match. How can that happen ? Sorry if this is off topic but no general forum.
