Transaction Costs in Forex and Equity Markets

In the stock market, for example, a commission on 100 shares or 1,000 shares of a $20 stock may be fixed at $40, making the effective cost of transaction 2% in the case of 100 shares, but only 0.2% in the case of 1,000 shares. This type of variability makes it very hard for smaller traders in the equity market to scale into positions, as commissions heavily skew costs against them. However, FX traders have the benefit of uniform pricing and can practice any style of money management they choose without concern about variable transaction costs.
