Is trading online worth it? Costs, spread and risks

Is trading online worth it?

It depends on what you mean by worth it. If the question is whether trading online earns you more than it costs, the honest answer is that for most private individuals it does not. In Europe, CFD brokers must disclose the share of their retail accounts that lose money, and the published percentages are generally between 70% and 90%. The analysis by national authorities on which ESMA based its 2018 restrictions spoke of a share between 74% and 89%.

If instead the question is whether it is worth training, understanding how markets work and making a few trades with an amount you can afford to lose, the answer changes. It depends on how much you spend on each trade and how much you risk. The overall picture, from the beginning, is in the guide to mindful online trading.

What are the costs of trading online?

There are five, and not every platform charges all of them.

1. The spread. It is the distance between the price at which you can buy and the one at which you can sell. As soon as you open a position you are already a little under water, and you only recover it if the price moves enough.
2. Fees. A fixed amount or a percentage on every trade. Some brokers do not charge them and earn on the spread.
3. Financing. If you keep a leveraged position open overnight, you usually pay a cost for each night. On crypto perpetual contracts it is called funding.
4. Slippage. The difference between the price you see when you place the order and the one at which you are filled, bigger in fast markets.
5. The side costs. Withdrawals, deposits, inactivity or currency conversion, when they apply.

Something worth knowing: «zero fees» does not mean zero costs. The price is paid somewhere else, usually in the spread. We look at it with numbers in the article on markets, instruments, orders and costs of online trading.

How much do costs weigh on a small account?

The smaller the account, the more costs weigh in proportion. A made up example, just to understand: on a 500 euro position, a spread of 0.2% costs 1 euro on opening, and about the same on closing. If you risk 1% of the account, that is 10 euros out of a thousand, you have already spent a sizeable part of the risk without the market doing anything.

The price has to move 0.8% in the right direction just to break even, in the small case. That is why, with little capital, it is better to make few trades, not many. How much capital you need to start is in how much money you need to trade online.

Does leverage make trading more or less worth it?

Leverage does not change costs as a percentage of the price, but it multiplies them as a percentage of your capital. With 10x leverage, a cost of 0.4% on the position becomes 4% of the margin you put in. And if the price moves against you, the same 10 amplifies the loss. It is the point to understand well before using it, and it is explained in leverage in trading.

How much do you have to gain to cover the costs?

A simple way to think about it is to look at costs in R, that is, in multiples of what you risk on each trade. If you risk 10 euros and costs are 4 euros, every trade starts already at minus 0.4R. A target that brings you plus 1R actually leaves you plus 0.6R, and a stop at minus 1R is actually worth minus 1.4R. Made up numbers, but the mechanism is real: costs shorten gains and lengthen losses. How to think in R is explained in R in trading.

Do you make money from online trading after costs?

Some do, but few, and almost always because they lose little when they are wrong, not because they are right more often. You will find the honest numbers, with the percentages declared by brokers, in whether you really make money with online trading. On top of that, you pay tax on gains: we cover it in is trading legal and how taxes are paid.

How can you tell if a broker is really good value?

• Look for the costs page on the site and read every item, not just the fee.
• Look at the spread on the instrument you will use, during the hours you trade.
• Check the share of retail accounts that lose money, which CFD brokers must disclose.
• Check that it is authorised: how to do it, step by step, is explained in how to recognize a serious trading platform.
• Before putting in real money, try doing the maths with a demo account: you see the cost of every trade without paying it.
