Broker Charts difference - possible problems

I have a small Big problem, here are 2 screenshots taken same time, at same our from 2 different brokers: MIG and Interbankfx, you decide where is the difference which I say it's VERY IMPORTANT.

A small hint where to look directly, bottom part where the RSI is 5, Bolinger of RSI is 20 and MA of RSI is 10.

Open them one above the other or near to see the difference.

What to think about this ? Each broker has it's own RSI, MA and Bolinger Band ? And I don't want to try other brokers because I'm sure I'll find more discrepancies.

Two things I can point out are 1) Time difference between the brokers. If there is a difference in daily bar open/close there will be a difference in calculation of indicators, and 2) Weekend data, IBFX has a small Sunday bar, does there other? I don't know. Weekend data like time difference will also give differing indicator calculation.

I noticed that IBFX start at 21.00 and Mig at 23.00 (their hours)

I attached the pics with Candles to see the difference, but that's not enough to give so Huge differences during the week. And people wonder why some strategies don't work for them.

Its the order in which you are applying the indicators. now hear me out. I know you are choosing apply to previous and first etc. but just have a look at these 2 ibfx charts. ibfx1 matches your mig. ibfx2 matches what you got with ibfx. it was all in the order i attached the indicators.

yes, it's ok now. thanks for clearing things out. I hope i'll never see this kind of discrepancies between brokers, for real
