Hello, I have a problem - when testing Expert Advisors on the currency pair audnzd I had to download quotes from the archive, but it did not work out well - the chart has become a "saw", with constant interruptions. Do you know how to fix it? Regards

Good afternoon people of the forum!

I am relatively new to trading on the exchange, only lost money, in general I decided to implement one idea, but to do this I need to know how to write code, mb it is already in the EAs, if anyone knows, guide me.

In general, the principle of martingale.

Opens on a sell or buy trade with sl and tp = 18

if it played in the + direction we instantly open one more position in the tp direction

if it played negatively, open a x2 position in sl direction after 15 seconds (if possible, this variable has to be set at the beginning)

All in all, if you will help it will be appreciated.


There is no need to spam.

i had to contact my broker and he gave me this link.
 
Which WinAPI call allows to run a command at the command line? I need to run a vbs-script from an indicator, the command there will be "cscript name_script.vbs".

It's the broker's job to give a good story. They are lazy and always blame the MCs.
 

The only thing I don't understand is how to calculate extrema of the MACD indicator, for example, instead of extrema of the price over n periods ?

extern int Quant_Bars=15;                       // Количество баров

   Alert("За последние ",Quant_Bars,            // Вывод на экран

   if(New_Time!=Time[0])                        // Сравниваем время
     {
      New_Time=Time[0];                         // Теперь время такое

I think I need to change HIGH and LOW to MACD in the key block... But I don't understand how ... all my attempts to goof around ended in nulling.

int Ind_max =ArrayMaximum(High,Quant_Bars,1);// Индекс бара макс.ц. 
int Ind_min =ArrayMinimum(Low, Quant_Bars,1);// Индекс бара мин. ц.

I understand that I need to create a MACD array...

double MACDBuffer[];

I've also seen such a string in other Expert Advisors

void CalculateMACD(int i)
  {
   MACDLineBuffer[i] = iMACD(NULL, 0, 12,26,9,PRICE_CLOSE,MODE_MAIN,i);

but I can't just measure one on the other...

Please, advise how to do it?

check out this article, it's not as simple as it sounds, and it's generally quite useful.

I took a look. it will take me a week to study it in details. but what's worse, i couldn't find any places that would be related to my task. i don't color the indicators, and i don't modify them in any way. i just want to find highs and lows on n-last bars. there is a hint of similarity in RSI_Extremums_Sample.mq4 but i cannot do that code. there are many unnecessary things, the indicator draws.... and i don't need it...
