Distinguish "Slip" and "Re-quo"

How do you tell whether the orders are open or closed with "Slippage" or "Re-quote"?
Is there a way to distinguish "Slippage" and "Re-quote" simply and precisely?

Dears, may I know why you don't like talking on this?

A re quote is an instant order AT market, you just getting whatever the price is AT market which can change before you actually get filled. SO you press buy or sell and before you get filled the market moves then broker will either just fil you at that price or pop-up with a re quote and confirm. Slippage can work with pending orders but is essentially get your order filled at a worse price than you bid or offered. You bid a buy stop at 1.10005 yet when you actually got the fill it was 1.10010 so 5 pipettes slipped which wouldn't be bad, but 5 pips might be a concern unless you trading news or something.

Hi Rtm, thanks for comment. However, that's not the point of the topic.
You know everyone knows true ECN brokers don’t re-quote in principal. However, do you have a method to detect?
So this thread is discussing how you can detect what you get is a re-quote or slippage.

Just place a limit order. Problem solved.

but sometimes you can get partial fills even on small sizes. I remember getting partial fill for something like 25,000usd. Seems we're no different than those big funds ! Liquidity issues they say, no guarantees in trading

As for slippage and re-quote:
Slippage could occur when price moved during execution, so your order is placed on the ladder in a range of prices, say between 1.12010 and 1.12025, since if your order is larger, it takes more luqidity to be filled and more time for the broker to offset it. In slippage you get an average price of your trade, so execution takes place from 1.12010 to 1.12025, and your average entry for say 300 lots is 1.12018, but you order is spread through the range between the start and end of execution it is not dropped on a single price point, as there is not enough liquidity per price point to absorb your order. But we should keep in mind that that is the pure example of slippage, when you cause the slippage with a large volume instant execution order, and given the way most retail brokers opperate, our slippage experience with them is not a direct result of our order being too big and moving the market, because we are not participating directly on the market, but rather their abillity to offset the orders in matters of seconds with the liquidity providers. And given the fact that many brokers operate as market makers and manage a book against client transactions, slippage becomes a completely different thing and is anothe weapon at the brokers arsenal.
Re-quote is when price has changed before your order got to where it is supposed to go, meaning before execution of the trade has started. You clicked buy 100 lots, however by te time your buy has travelled and started being proccessed, market is at a different level. Broker is quoting you new price to trade, because by the time you demanded the particular price, market is no longer there.
They both can have same effect on trading, but requotes do not speak good about your broker and your connection to the broker. Requote is a lagging experience, slippage is exactly what it is called - market slipping off your trades. Slippage is quite normal to experience for large market orders, but still anything too large, maybe more than 1-2 points at any time/condition is unacceptable in my opinion, if we exclude high-impact news, but thats just some seconds.
But I say once again, slippage and requote is one thing in theory, but at the arsenal of a non-honest broker it is sometimes just an excuse for messing with your jobs.

Yes this is true! It all comes down to the broker I guess too and what model they use for your orders.

yes, not the most meaningful discussion for retail traders. better talk about which brokers give the least slippage and/or requotes and are a little more reliable for our pockets. I see that you have made good choice for your public accounts.

Indeed! I personally would say Tickmill has given me the best all around trading environment in terms of spread, execution, withdraw etc. and YES on that note I just like to let me actions do the talking(TE).

Why do you use TickMill, which is regulated by Seychelles? Did you feel the risk?

Because they offer the lowest spread, best execution, leverage, server quality and overall trading experience is top notch. I don't trade as much with them as other brokers but I am not at all concerned the fact that they are regulated by the FCA

I will be trying them more in the future. I wouldn't put any serious ammount of capital in a seychelles regulated broker, but to be honest - why would anyone want to put too much capital on one single broker? Diversification in every aspect is part of this game. I am sure that rtm is trading multple brokers and does not rely only on one.

It's easy to spot if a broker scam organisation is giving you the monkeys and can be verified in only a few steps.

First, look down at your feet, are your pants mysteriously around your ankles?

Second, do you feel like you had a Vindaloo the night before?

And third, there's an empty pot of KY on your bedside table?

If you answered yes to all 3 questions, it's time to find a new broker which isn't based in some mickey mouse country.

Or as Rtm said, use limit orders.
