Hi MrLong & all,
Time to post my optimized version of 1.08. Goals of my modifications: lower cpu usage by eliminating redundant calculations and simplifying mainenance of the grid by an alternate method of drawing the cells and placing the columns within the cells.
Multi_10_4_EAv1.08rsi_stoch_JM.mq4
modifications here:
- split func DisplayGrid() in two for runtime optimization: CreateGrid() and UpdateGrid()
- replaced redundant function calls in CreateGrid() and UpdateGrid() to further optimize cpu usage
- declared extern int GridMethod to switch between original code and simplex code (temporarily)
- simplified positioning of columns in grid by arrays
- simplified drawing of grid background: drawRectangle()
- functions LabelCreate() and LabelSetText() to simplify object management
- On my display grid columns of open trades and corr. pairs were intermingled. Fixed this.
- patched functions CloseAllButtonBeenHit() and DeletePendinglButtonBeenHit() for a flexible positioning of close buttons
- changed some color settings, just a matter of personal preferences without public value
List of new functions:
- drawGridBack: draw the grid
- drawRectangle: draw a rectangle consisting of labels
- LabelCreate: name says it all ...
- LabelSetText: name says it all ...
- CreateGrid: replace DisplayGrid in init()
- UpdateGrid: replace DisplayGrid in start()
List of modified functions / code sections:
- global declaration section: new var GridMethod
- global declaration section: several new declarations - look for the comments
- init(): changed some colors and coordinates to my personal needs. Called CreateGrid instead of DisplayGrid.
- start(): Called UpdateGrid instead of DisplayGrid.
- CloseAllButtonBeenHit(): replaced hardcoded coordinates
- DeletePendinglButtonBeenHit: replaced hardcoded coordinates
NO changes were applied to trading decisions, etc. - just cpu optimization and gui stuff.
Some remarks:
When reviewing my modifications browse for the string
simplex - I marked any change / new function I placed in the code (hope so, at least
).
By switching
variable GridMethod to values 0, 1 or something else you can switch between MrLong's original version and mine. This is thought to be a temporary measure to help MrLong integrating my stuff.
Settings: 0: simplex runtime optimized and simplex GUI / 1: simplex runtime optimized, MrLong GUI / else: MrLong original
function
drawRectangle: replacement for drawCell(). I created this because drawCell sometimes changes horizontal and vertical positioning coordinates when changing height / width settings. Extremely hard when it comes to code maintenance.
bool useWebDings: function drawRectangle has two different methods of drawing a cell implemented. The default method is called when useWebDings == true and works based on the TrueType font
Webdings. If you don't have this, set useWebDings == false. Then the alternative method base on WingDings will be called. Rectangle heights and widths of both methods are not compatible! You cannot set width / height on pixel granularity, but on character granularity. Will not fit every possible use, but should be sufficient for creating text oriented grids.
Arrays gridCol1, gridCol2, footCol1, footCol2: supply one single point in the code for changing horizontal column coordinates. No inline patches necessary.
I set
grid size to fit the 1366 pixel wide display on my elderly test machine. These are subject to your personal changes.
I set
columns positions to allow for long strings under
correlated pairs.
@all: this version is meant primarily for MrLong to integrate in his v 1.09. That's why there are several if statements to switch between his version and mine. And I set my preferred colors in init() because I did not want to mess up his code too much. So if you don't want to bother about this just stand by until MrLong uploads his next version.
@MrLong: any question that might appear during integration is welcome!
That's it! Have fun testing & integrating!
Cheers, Jürgen
EDIT 2013-03-26 16:50 CET: upload a new version that fixes 3 issues. Delete old version.
