OnCalculate function not found in custom indicator?

There's a given Moving Average indicator, it works in MT5. Now I'm trying to add a text object tagging the MA value of last bar. #property indicator_chart_window #property indicator_buffers 1 #property indicator_plots 1 #property indicator_type1 DRAW_LINE #property indicator_color1 clrWhite

Mql4: after parameter changed on the fly, failed to redraw chart?

I added an edit box to adxvma indicator, allowing change adxvmaperiod on the fly, and it tested ok, but then I failed to redraw the chart. I've successfully fixed this kind of problem with a most simple ma indicator, and it has a oncalculate() structure. But with this one, I admit it's too

can tester communicate with real file and folder? (for debugging)

I have an EA from others, which copies, reads and writes csv file in MQL5/FILES folder under metatrader. It's too complicated, much over my coding knowledge but still I want to revise it a bit. So I did a simplified experiment and I found that, with tester, I can not copy file to the real MQL5/FILES

in indicator, line draws but arrow does not

There's a given MACD indicator , which has 4 buffers and 2 plots ( ExtFastMaHandle and ExtSlowMaHandle don't draw). Now I'm adding another 2 lines (actually 1 histogram and 1 line) and 2 arrows, making it 8 buffers and 6 plots. The following is my try. In OnCalculate(), with debugging, I found the 2

why arrow does not draw in indicator?

Just begin to learn mql5 , the following is a simple test, the data is there, why arrow just doesn't draw? #property indicator_chart_window #property indicator_buffers 1 #property indicator_plots 1 #property indicator_type1 DRAW_ARROW #property indicator_color1 clrWhite #property

close[] when converting mql4 to mql5 ?

Just began to learn how to convert mql4 to mql5. I learned how to deal with close[] in OnCalculate(......const double &close[], ......), with "ArraySetAsSeries()". But in my own function "draw()", I also have to use close[], so I tried : void draw( const double &close[]) { ArraySetAsSeries (close

what really happens when dragging another currency pair to current chart?

I just wrote an indicator for a friend, which draws several TEXT objects near/at each Low[] of several bars, only on D1 chart. I also added a fixed "padding" to move those objects a tiny bit away from Low[] price. This indicator works fine for me. But my friend has a habit: he often opens a chart

differentiate mouseclick and ctrl_mouseclick, my code does not work

void OnChartEvent ( const int id, const long &lparam, const double &dparam, const string &sparam) { string lastmove; if (id== CHARTEVENT_CLICK && lastmove!= "ctrl" ) { Print ( "clicked" ); lastmove="clicked"; } if (id==

array or loop problem?

Senario: in the current currency pair, open multiple positions, then manually close them one by one. The following function recountorders() works fine and I can test with ArrayRange(sl,0) showing order counts of the current currecy pair correctly, and it turns zero when all orders closed. int sl[][

(solved)array out of range? not price related, maybe about OrdersTotal

Please close this dumb question..... the last two lines, I should use poscount instead of i. I'm working on this code, using a CButton, my purpose: when new position (not including pending order) added to the current symbol, or stoploss changed in any of open position of the current symbol, this
