The intention of the Smart Trading Journal is to model all trading activities and account transactions of daytraders, institutional traders, private traders and/or everyone who is participating in short to longterm financial investments alike. Its comprehensive statistical calculations give valueable insights and performance measures every serious trader should know about. The individual trading results are hence part of the optimal portfolio and position size calculations which can be of great significance in a traders investment plans. The concept of R-multiples which has been introduced by Van Tharps "Definitive Guide To Position Sizing", is the foundation to many calculations as well as the risk and objective simulation in particular. Apart from that it is advisable for every trader to become familiar with statistical trading principles in general. The available scoring and commenting features will help to develop a personal trading style and improve on every trade taken. Finally the Smart trading Journal is meant to be the one tool where all investment activities are documented and tracked without being dependent of a specific brokers or banks API.
