Minimize All Trading Business Costs

Some trading systems have only marginal profitability, and trading implementation costs (commission, spread, and slippage) can be the difference between profitability and making a loss. With the easy availability of modern electronic brokers, and fully-automated trade processing and execution, it is definitely worthwhile looking for a very low cost way to implement your trading system. High commission, wide spreads, and large amount of slippage can be reduced considerably simply by carefully choosing a broker. This can be the difference between a system (especially a high frequency one) being useable or not. Paying too much for trade implementation is an avoidable way to lose money.
