Beginner - Error open parenthesis expected

New comment
Francois Dominique Izaak Huibregtse  

Hello,

By reading through this website i am trying to make a (hopefully) very simple indicator. This is for learning purposes as I am a total beginner.


My first step is that I want to store the closing price in a variable at a specific time. Later on I want to compare this closing price to a closing price an x amount later and generate a buy or sell signal.


But I get an error at the first step. There is an openparenthesis expected at the "If" statement. But when I read me MQL5 reference for the "if" statement it seems to match my format.

Can someone help me out?

You have not used the  TimeCurrent function correctly

   if(timezero == TimeCurrent())

Hi Everyone,


So I have been trying to make my own indicator based on the above.

-If the close price at a specified time is higher than the close price x-amount of minutes back, then I want to plot a up-arrow on the chart.

- If the close price at a specified time is lower than the close price x-amount of minutes back, then I want to plot a down-arrow on the chart.

The idea is that the arrow has a similar style to that of the fractals indicator.


The code seems not to have any errors. Yet, no arrows are generated on the chart. Can someone point me in the right direction as to what I am missing? (ps. when I attached the indicator the input parameter timex is filled in minutes: for example 1320mins in order to set the time to 22:00hrs of the current day). 

Also any tips on how to get the close price from an array back at a specified time? Currently, I simply use close[24] to get the closing price of "array entry 24".
