I’ve been messing around with Oanda’s FXGame for 3 weeks now, working with candlestick charts, but lately I’ve noticed I’m not using the same candlesticks as everyone. When I look at the candlestick charts elsewhere, I see that most of the time, the open of a candle isn’t at the same level as the close of the last one. How is that possible? It’s as if the candles weren’t continuous… 
Here’s a screenshot of a candlestick charts provided by Oanda:
Does anyone have an explanation for me? Thx!
4H and higher time frame candlesticks may vary between brokers because all brokers do not opens the same time on Sunday. 1H and lower tfs will be the same.
Alpari 4H candles starts at - 02:00, 06:00, 10:00…
FXDD 4H candles starts at - 01:00, 05:00, 09:00…
I’m no expert but I have been told it might have something to do with a lag in the data feed between sessions. I was trying an MT4 broker and it was driving me nuts (I’m somewhat of a perfectionist :)), so I finally switched back to Dealbook 360. I noticed a similar problem on some of the other platforms I tried, although I can’t remember which ones off hand…
All Oanda users are the same.
But when we look at MT4 charts the open, close, high & low
are set up on the bid price, whereas Oanda’s is set up on the average
price.
Also different brokers have different feeds, at this time in your
development just stick to one set of charts & as time goes on
you will get to appreciate other charts.
Good point.
There is nothing wrong with these charts.
They can be traded in the traditional way without problems.
Thx for the answers! Now I have to figure out how candlestick patterns apply on the charts I use. ><
Well, you can always look up my thread :
