ECN Price Feeds VS Market Maker Price Feeds

Hey guys and girls. I am fairly new to forex My broker is an ECN broker(FxChoice) and I execute trades off their MT4 web platform. However, I do my chart analysis on a live GMT + 2 Oanda(a Market Maker) price feed on the desktop metatrader 4 platform.

I have been reading about ECN and Market Makers and from what I understand, ECN brokers are better than Market Maker brokers because ECN has direct interbank access and simply passes prices from the interbank market right to retail traders with no requotes, no price manipulation or mark up and low spreads etc. Market Makers have access to interbank as well but they "make" or "set"prices, and may manipulate price wide spreads, and hunt stops etc.

However, all the things that I mentioned above have to do with the execution but not the actual price levels on the right side of the charts. My questions are: 1. Are the price feeds and price levels on the right side of the actual chart from Market maker brokers that much different from the prices of ECN broker charts and Interbank prices? and if so by how much? a few micro pips? I ask this because my strategy is partially based on round numbers and I just want to make sure the price levels and round numbers that I analyze on my Oanda live price feed are actually accurate and at least close to price levels and round numbers that interbank charts have.

Thank you so much for your help. I will be posting my strategy here soon. It has been working well. Very much automated and objective with little subjectivity. I have videos as well. All free. Not selling anything or collecting emails or whatever. Thanks in advance for your help.

No one like market makers mostly because they don't like to pay when you earn a lot and trying to withdraw.
(they have to share with You part of they own earnings.)

second problem can be et these differences on the chart, for ex. try to feel price action with 4 and 5 dg broker....
same problem happens with differences in price, some time You will be working with totally different chart, different chaps, or even shifted time zone for amateur broker will mess up all candles above H1. -> H4, D1, etc.

How much are the differences ? it really depends on specific case. This need a analysis to prove they existence and how big they are.
i wont do it for you.

Do You have access to them? I dont think so.

Thanks for your input. I did a little research and watched an in depth video on FXstreet.com that clarified everything for me. I now understand. I have also recorded my videos for my system. I will post it today and see if I can have some people test it with me although everyone here seems a bit set in their ways haha

bad time for fast response form ppl. this weekend is so lazy...

Just using general logic, if you can stay away from doing business with parties that profit from your loss, you'll be OK

Try a DMA or a ECN broker.
