What Are Spreads?
Understanding spreads:
The spread is the main difference between the bid price (this is the selling price), and the ask price (this is the buying price), and is quoted in pips.
Example: The quote of EUR/USD for the moment is 1.2222/4; the spread here is clear enough to be at 2 pips. And if the given quote is at 1.22225/40, the spread is at 1.5 pips.
Spreads are how the brokers earn money. The wider spreads come from a higher asking price, and from a lower bidding price. The aftermath will be that the trader will pay more when they purchase, and get less when they sell; this makes it harder to earn profit.
Spreads are so important because they affect the return on the trader's strategy in such a significant way. The sole interest of the trader is to buy low and sell high. The wider spreads would mean that the buy is higher and would have to be sold lower. The half-pip in the lower spread does not sound like much, but this can make it easy to see the difference between the profitable trading strategy and the unprofitable trading strategy.
To know the trader's cost, one can use the "Spread Cost " to see the difference spreads have on one's returns.
It is in your favor if the spread is tight, but only if the spread is coupled with astute execution.
The policies of the spread differ substantially from broker to broker; the policies are not exactly clear. It can be difficult for the trader to compare brokers. Most brokers offer spreads that are fixed, and they are guaranteed to stay the same, whatever the market's liquidity.
Some brokers offer the traders variable spreads that depend on the liquidity of the market. The spreads are tighter if there is good liquidity in the market, but the spread widens if the liquidity dries up, too.
The choice depends on the trading pattern of the trader, whether they choose the fixed spread or the variable spread. If you only trade based on news announcements, then you are better off with a broker with fixed spreads.
Finally, the Forex prices, at present, are dictated by the interbank Forex market, this is where the spreads are often variable, relying on the current ticket size and liquidity.
Most brokers just try to reduce things by providing constant spreads to their clients, guaranteeing that there is no slippage. This, of course, is fine. On the other hand, there is no "free lunch". The trader has to do some work to investigate, if they can, to know who's really paying for this so called-guarantee.
