Are You Under or Over Trading?

Proper position sizing and risk management is the key to making consistent profits in the stock market. Most people think trading is all about looking for the perfect stock and timing your entry perfectly. But in fact, a system with random entries can be profitable as long as you have good money management rules and follow the golden rule of trading, let your profits run and cut your losses short.

How much risk can you tolerate on each trade?

Trade Size implements a Percentage Risk Model that ensures you don’t lose more than a predetermined percentage of your trading equity on any given trade. Traders use this approach to determine their position sizes.

What do you need to know to calculate your position size based on the Percentage Risk Model?

- Your Total Capital or Account Balance
- The Percentage of your capital that you’re prepared to risk (0.5%, 1.0% or 2%)
- The Initial Stop Loss Price. In a Long position this means how much should a stock go down before you exit a trade.
- The Entry Price at which you will enter the trade.
