pako:

The bar number of the lower fractal is known

From it, search in the loop for the first high corresponding to the low of the known fractal

This can be done, but I would do vice versa. I.e. first find the high of the previous (formed) candle, and then the last fractal down. If they are the same, put a point.
Alexey Kozitsyn:
We could do that, but I would do the opposite. I.e. first we find the high of the previous (formed) candle, and then the last fractal down. If they coincide, we put a point.

I don't understand. I thought that's what we were doing in the condition.

if( High[i+1]==Low[isFractalDn()])//максимум первой свечи равен первому фракталу Dn
How should one write it?

Where exactly is there one line

Sorry, got confused with the terminal. Of course you only need to enter the LOGIN from MQL5.community.

Thanks, but it's not showing any signs of life...maybe I did something wrong?

There could be several possibilities:
  1. You have a 32-bit operating system. In that case you are not allowed to go.
  2. The time is short - it takes two minutes to join the cloud.
  3. Possible ports closed by firewall - need to look at agent logs.

well the system is x64 because i have 8gb RAM and the OS is win 10, ok thanks i disabled firewall now i will try again !

Do you know how to find out the TCP port I just downloaded the metatester separately ...
