In the Formula Editor dialog box, you can enter the formula name, password, formula content, additional lines and other information, and you can also select the formula type and line drawing method. The details are as follows: the formula name is used to identify the indicator formula, and it cannot be repeated, with a maximum of 16 characters. The keyboard wizard also uses this name to select a formula. The formula description simply describes the purpose of this indicator. Password protection If it is not checked before, the formula is not encrypted. Click Password Protection to check it. Enter the password at this time and the formula will be encrypted. For encrypted formulas, you must enter a password to see the contents of the formula. To delete a password, click Password Protection to make the box in front of it disappear. Parameter formulas can take parameters, and the names of parameters can be entered here. Minimum value of minimum parameter Maximum value of maximum parameter Default value of parameter formula type specifies indicator formula type. When users define indicators, they usually choose other types. Line drawing usually selects the superposition of the auxiliary image or the main image. When selecting the main map overlay, the indicators will be superimposed on the K-line map; When a subgraph is selected, the indicator can only be displayed on the subgraph. The position of the coordinate line is only valid for the index of the subgraph, and the specified value is displayed on the ordinate of the subgraph. The default time is "Automatic", that is, the system sets the horizontal coordinate line according to the actual situation. Other Y-axis boundaries draw horizontal lines with values of 1, 2, 3 and 4 in the secondary image. The introduction formula creates a new index formula based on the existing index formula in the system. Insert Function Displays the Select Function dialog box to find the required function in the built-in function set of the communication letter. Test the formula and check the grammatical errors of the formula after writing it. When dynamically translating indicators, algorithms or functions input by users, Chinese semantics are prompted synchronously. After the test results are tested, prompt "Test passed" or display an error message. Parameter Wizard When creating a new formula, the user can use a paragraph in the parameter wizard to describe the meaning of the parameter to be set. This explanatory text will appear where users are allowed to adjust parameter values, including conditional stock selection, index sorting, adjusting index parameters, selecting indicators, selecting trading system instructions, selecting conditional stock selection instructions and so on. Instructions for use can add users' opinions on the use of indicators.
