Pipruit: I understand about pairs, but what are transaction costs? Commander in Pips: Well, it’s a bit early to talk about that in detail, but I give you fast forward look. Let’s return to quote board in exchange centre: Currency We Buy at We Sell at 1 EUR 1.35 USD 1.37 USD 1 GBP 1.65 USD 1.67 USDSee – there is a double quoting, one price is for buying the foreign currency and another for selling it. The difference between buy and sell price calls “bid/ask spread”. If you will buy Euro here for 1.37 (because bank sells Euro for 1.37 currently, this is “Ask” price) and at once sell it at 1.35 (because bank buys Euro only for 1.35, this is “Bid” price) you will get a $0.02 loss – that’s your transaction cost. In fact, you do nothing, because you stand with the same position - you Buy Euro and Sell Euro at the same time. Even so, you’ve just lost 2 cents. So, for major pairs the Bid/Ask spread on FOREX is very tight - usually 0.0001-0.0003, but for exotic pairs it’s much wider. It means that if you would like to make the same transaction with Thai baht, for example, you can get greater loss instead of 2 cents as it stands with Euro transaction. It can be 50 cents or even buck. You should remember that if you ever intend to trade exotic pairs. We’ve just talked about Bid/Ask spread but there are other sorts of transaction costs that exist also. In general remember one simple rule – “the higher the transaction costs, the lower your potential profit from the trade”. P.S.
