When setting the parameters of each trading order, the trader determines the conditions for its execution for the broker: the price at which you need to enter and exit the market, as well as (if necessary) the opening/closing time of the transaction. Alas, in the search for a balance of supply and demand, the market corrects everything in its own way.
At the same time, beginners experience the whole range of feelings - from panic and depression to claims against the broker, but in fact this is a normal market phenomenon − slippage. It is impossible to completely get rid of this effect, but it is possible and necessary to fight and even use it profitably.
So, the main subject of the conversation
Slippage in trading is execution at a price different from the one stated in the trading order and from the current quote. As a rule, the real price of the trade turns out to be "worse" than the declared one, but sometimes the difference can be positive (in favor of the trader), depending on the direction of the trend and the type of position being opened.

The first problem arises in the process of receiving your trading order to the interbank - during the processing of your order to the broker (liquidity provider), even if it is a fraction of a second, the price changes, as a result, execution at the price you stated becomes impossible.
You will have to open (or close) a deal at current prices, and if the market goes in the direction of your deal (positive slippage) - get additional profit, if the price went against you (negative) - the result will be worse. The longer the delay in order execution, the more the current quote will change and the difference with the order price will be greater.
Reasons for slippage in trading
We remind you that in the financial market, the seller offers a more expensive price, and the buyer is looking for a cheaper place. In most cases, slippage is not the "machinations" of the broker (although this also happens), but a consequence of the consistent execution of trading orders.

Each purchase transaction means that there should be an offer on the market for the same (preferably!) the price and in the same volume. When opening a position to buy/sell an asset, the market must select the necessary volume of opposite orders at the price you need, and if this volume is not enough, the balance will be executed at the "nearest" suitable quote - this is the effect of "slippage". Such a price can be considered optimal only from the point of view of the market, but for a trader this means a partial loss of profit in 70% of cases.
It is for the optimal execution of trading orders that the broker collects small orders in a certain range in larger "pools" before withdrawing to the interbank market and works with them at the same price. As a result, the slippage in trading for each specific order may be different. In a fairly liquid market with a large number of participants, it is possible to quickly find counter orders of almost any volume, then the slippage will be minimal.
You need to understand that not only the opening/closing price slips, but also the price of setting Take Profit/Stop Loss, so it is not always possible not only to enter the market, but also to fix a deal at the stated price. Pending orders suffer from this problem much less.

What is the danger of slippage
Let's assume that each trading order and its Stop Loss slip by one point. Of course, this is not critical for medium-term transactions and long-term trading strategies, but it can be a disaster for pipers and even for scalping strategies on M15-M30. Taking into account the spread costs, the loss of tens or even hundreds of points per day can completely destroy the profit from short-term transactions.
If the stated price is in the zone of strong levels, then a strong slippage may incorrectly set your Stop Loss and at the first rollback your transaction will be closed with a loss. During periods of high volatility (news, opening/closing sessions), the number of participants increases sharply, and most often in one direction, so the risk of slippage increases significantly.

Attention - requote
There is another situation on the market that looks like slippage, but has a different fundamental reason. Recall that there are two types of execution of a trading order:
- Market Execution - the transaction is opened in any case, but at the market price.
- Instant Execution - the broker is obliged to open a position at the order price, that is, to ensure zero slippage.
Market Execution an order is always executed and the market decides how profitable it will be for the trader. The required volume to overlap your application is selected automatically. If the opposite volume is not enough at the stated price, then the volume of your transaction is divided and sent to several liquidity providers. As a result, the trader receives a weighted average price for the transaction, which may be significantly worse or better than the stated one. The only advantage of Market Execution orders is the fast execution of orders.
The Instant Execution type provides for strict compliance with the price for the entire volume of the transaction. However, if there is no such price on the market at the time of receiving a trading order (or there is not enough volume), the trader receives a request (in an interactive form) to execute the transaction under other conditions. This situation is called a requote. Until the trader confirms the price, the order will not work. Of course, while the trader is thinking and making a decision — the market is moving, the terms of the transaction become irrelevant, you can get into the next requote, etc. The result-trading may be missed. This is a serious problem in both the fast and low-liquid markets.
Nevertheless, everyone who has experience in direct exchange trading believes that for any type of trading, the optimal type of order execution is Instant Execution. Only you need to "not be greedy" and indicate to the broker an acceptable deviation from the price (usually up to 5 points). And they prefer to deal with possible requotes in short-term trading with technical means and practical experience.

How to reduce possible losses from slippage
The main thing is not to try to fight with these phenomena, you need to learn how to work with them. So, in order for potential losses to be minimal, you need:
Set the maximum allowable deviation from the requested price (in points)in the trading terminal
If the price deviation (at the moment) is greater than this parameter (critical slippage), then such a transaction will simply not be executed. Yes, you will not make a profit, but transactions with a high probability of loss will not open.

Trade with pending orders: Buy Stop/Sell Stop and Buy Limit/Sell Limit
Buy Stop/Sell Stop orders require a clearly set price and are considered more problematic than limit orders, which allow a qualitative assessment of the "higher/lower" type. Deferred trading orders are sent to the broker in advance, part of the liquidity is "reserved" for them to some extent, of course, provided that transactions are actually withdrawn to the interbank market. It is these orders that have the highest chance of working out at the stated prices.
Choose trading on higher periods
If even 1-2 points of slippage can be critical for a transaction on M5 with the usual margin of profit (5-10 points), then on timeframes above M30 such negative consequences are almost invisible.

Do not trade during periods of problematic liquidity
Any non-standard situations are dangerous: news, planned and force majeure events, opening/closing of trading sessions, a low-volatility market on holidays. Those who catch active / weak volatility or try to trade exotic assets should be prepared for an increase in slippage and the probability of requotes several times.
Use a volatility filter
If you still risk trading on a speculative market, then you need to choose the entry points with the maximum margin of profit. For example, if your average profit per trade is 30 points, then a slip of 10 points (for example, during the news) will take almost 30% from your profit. You can trade only part of the news, with a more explicit and reliable forecast, which give, say, 60-70 points, then the percentage of losses will be significantly lower. The same applies to individual instruments − we recommend trading only on days (or periods) of maximum volatility.

Use a stable internet connection and reliable technical equipment
Slow execution of orders due to communication problems can cause slippage of several dozen points, so we recommend that you also have backup communication channels, and scalpers should definitely trade using VPS.
Only if all this does not help, and situations of strong slippage are systemic in nature and occur even in a stable and liquid market, then you can think about...
Change your broker or trading account type
Choosing the right provider and setting the minimum deviation level is crucial. It is unscrupulous brokers who often create "fake" requotes − an artificial delay in the execution of an order, allow critical slippage even with high liquidity, practice canceling the results of transactions and other problems. Such a broker "holds" just the most profitable deals, since the trader's loss is his profit. It is necessary to monitor the behavior of quotes during speculation: the broker's warning that at such moments the correctness of the execution of orders is not guaranteed, and the results of the transaction can be canceled is usually indicated in the contract in the smallest font-read carefully!
By the way, even if you plan to work only with long-term transactions, we recommend choosing a broker that openly supports scalping and news trading. It is such providers that are particularly demanding of trading conditions and provide high speed of order execution.

Conclusions
Slippage in trading is an objective phenomenon, it is just considered a "healthy" sign of real trading on the stock exchange, and this problem is also present on ECN accounts. No serious broker withdrawing transactions to the interbank market guarantees the complete absence of delays in execution and requotes and will not compensate you for losses from these phenomena. The proposed methods will help to protect your deposit from slippage as much as possible, unless they contradict the trading strategy. Otherwise, adjust your trading methodology to the real market.
