what causes such bad performing Candles in 5M Chart?

excuse my simple question, but one of my Brokers`s MT4 has such bad peforming 5 M Candles
since I updated the MT4 ( it also happens in higher TFs, but not that bad like in the 5M )

here is a screenshot

my other Broker´s Charts and Candles are just fine....

I am a bit suspicious....

Your broker provides quotes with only 4 decimal places, so such chart on M5 is pretty normal during non-volatile time.

I am sorry, but at the same time, 2 other Brokers are providing clear Charts in the same TF


so I believe, there must be another reason

Those two other brokers have 4-digit quotes too?

Seems obvious to me that Enivid has come up with the most likely explanation. To confirm, take a look at the tick volume for all three brokers. I think you will find there is a huge difference between them. Its the same as comparing a thinly traded stock with a heavily traded one or two commodities.
