Disable chart scaling
I try to disable chart scrolling and scaling by the ChartSetInteger function with the property CHART_KEYBOARD_CONTROL (in MT4). Disabling scrolling is successful in this way, but unfortunately scaling cannot be disabled in this way. Every time you press "+" or "-" on the numeric keypad, the chart
Price scale changing
Can we detect that the scale of the price axis has changed when the price rises/falls outside the original interval on the price axis? I thought this should be handled by a function OnChartEvent with id CHARTEVENT_CHART_CHANGE, but unfortunately not
What derived class
I need to have a base class and several classes derived from that base class. Since the derived classes are derived from the base class, I can assign the variable (pointer) of any derived class to the variable (pointer) of the base class. So far, everything is clear. Is there any way to find out
STAT_MIN_MARGINLEVEL
I'm a little bit stuck with the function TesterStatistics (STAT_MIN_MARGINLEVEL). The documentation says the function returns "Minimum value of the margin level". What this exactly mean? I thought that the value is the minimum margin level but it seems to me it's not true. If I run a backtest where
Pointer to the function
Is there a possibility to set a pointer to the function as a class method (not a static method )? This example is without problems but only with a static method: typedef void (*TAction)(); class Foo { private : TAction m_Action; public : Foo( void ) {m_Action=Bar;} static void Bar() {
A custom indicator as a resource

Get indicator's buffer color
Hello everyone, I'm looking for a function in MQL4 that returns a color of a specific indicator's buffer. Something like PlotIndexGetInteger(plotNr,PLOT_LINE_COLOR) in MQL5. I know there is a constant indicator_colorN but if I change the color in the input window (tab colors) the indicator_colorN is
Leverage for each symbol
I know it isn't a new problem but with new ESMA rules (about leverages) it became "interesting" for me. Generally now we have a different leverage for each symbol. But I know only the function AccountLeverage() (or with the same result AccountInfoInteger(ACCOUNT_LEVERAGE) ) that provides something
Is there any way to load programmatically entire history (of a Symbol and a Period) from server?
I'm looking for programmatically solution of loading entire history for a symbol and a timeframe from server. I can do it manually by opening a chart with the required symbol and the required timeframe and then (unlock Scroll the chart button) by pressing Home and multiple pressing PgUp until I get
