The article is devoted to the tactics of forming and using forecasts of changes in prices of financial instruments on the Forex market using the multitrading system developed on the MetaTrader 5 platform. The basic element of the multitrading system is the Analytical Window with 17 technical analysis indicators distributed over 4 sections. Three Analytical Windows with chart periods that are successively increased by 4 times form a Trading Group from the Operational, Tactical and Strategic Windows. Three tactics for selecting strategies allow you to determine the period of the interval chart of the Strategic Analytical Window, in which a unidirectional price change (oscillation) is predicted over 4-8 time intervals. Trading signals for choosing tactics and making operational decisions are formed by indicators of all windows of the Trading Group. Forecasting Objects specialized for charts of different periods are used to make forecasts of trends in the formation of oscillation groups for two intraday, two short-term, one medium-term and one long-term strategies. The properties of Forecast Objects ensure that they are displayed in the windows of all junior and two senior periods. The set of Forecast Objects includes Trend Start Marks, Regression Channels, Andrews' Pitchforks, Price Vectors with Start and End Price Labels, Trend Reversal Levels, and Recommended Deal Activity arrow indicators. The state of Forecast Objects is updated in the Forecast Window, which is obtained by reversibly modifying the Analytical Window. The methodology for using Forecast Windows in forming and verifying forecasts for 6 multitrading strategies has been successfully tested. Separate chapters of the article are devoted to tactics for using single oscillations and their groups, such as correction packages of four oscillations and trend blocks of two packages. A special section of the article discusses tactics for reducing risks when trading in conditions of stability and volatility.
