No, not all of them. Not so long ago I was unpleasantly surprised when a Take Profit was executed with negative (against me) slippage. It was on the news. Tech support explained that this is normal and limits (take profit by definition is a limit order) are executed as MIT (Market If Touched). In other words, when the price touches a limit order level, it is executed as a market order. Unpleasant of course, but there is nothing to do.
thanks for the quick response. It does widen my horizon I would say.
This slippage is now always there, no matter when do the trade or whether it is limit or market, it all executed at a worse price, with certain amount of distance.
I open size of 0.01 so the market depth should be enough to take it, somehow it never executed at the price given by the quote any more.
Am I on the blocklist of LP now? lol

Thank you sir. That's the thing: I thought this level of manipulation is only possible with MT4 but not MT5? At least that propaganda is already nerratived in this way
Also I feel manipulating with such big slippage is too obvious. It also made the "limit order" a joke. I am not sure if they really intended it or it is a bug. So I am still waiting for a response. All I know is that new registered users does NOT have this issue, I have verified that.
Again, the issue is that EACH of my order is now imposed with the big slippate, including the LIMIT order.
I searched around, the situation is similar to

The broker still didn't answer this question. I suspect it is because I have traded big volume and have been successful so they blocked me, but I want to confirm.
They can just explain why they did that. That would be better than imposing this hidden spread!!!

aha, the broker mentioned something about volatility, low liquidity, and recommend to find a VPS to prevent this from happening.
They keep ignoring when I mention this happens to every of my order, even LIMIT order and I am already using VPS.
Seems this broker doesn't have any clue
Get a new broker if that happens often. And read the links that were posted in first responses. Some brokers do not apply the same rules to limit order prices. But i believe that this is mqs issue since it is mq that allows the ability for brokers to do these fraudulant actions.

Hey folks,
I have encountered a werid issue. I have registered with a broker who claim to be A-book broker using STP model. I opened RAW SPREAD account supposed to have ECN access to instruments
It was trading fine until quite recently, ALL my position opened got slippage. So I made some test with limit orders. Even that has slippage! It will not be executed at price equal or better. It ALWAYS get executed at a worse price with high slippage.
In the attachment I pasted what happened to limit order: It was a sell limit order of size 0.01 (minimal size) at 2662.50, but when the bid price reached 2662.50, the open price was shifted to 2662.29.
So even for limit orders, it is as if they open position with a forced worse price. Is that what Deal Desk is doing? But I heard MT5 ECN brokers won't have deal desk. Can someone help me understand? Am I scammed?
Currently I am asking for investigation but after 4 days, still no response. I don't know whether it is allowed to name the broker here so I will hold the broker name for now. It is a pretty good broker otherwise.
Should I ask MetaQuote team what's going on?
