Then draw a horizontal line.
Why do you need any buffers and their recalculation? ObjectSetDoubke(0,myHLine,OBJPROP_PRICE,concrete_price_value);
the user will see the line, you won't waste time recalculating the buffers, everyone is happy and happily disperse
PS/understand correctly - indicator buffer, it's for transferring(sharing/sharing) the results of calculations performed in the first place. Drawing a horizontal line of length N is different
the line should be a curve, i.e. its first value should show current Bid+size, the previous value - Bid+size tick back
And I will need this line to take indicator values for my EAWhat is the correct syntax for a for statement when an expression consists of several parts?
I'm writing it like this:
It doesn't compile.
I write it like this: for(int i=candle_two_index-1,int k=0;i>=candle_two_index-candles_oneside;i--,k++)
Try to compile int i=candle_two_index-1,int k=0; or int i=1,int k=0; separately without loop - you will understand the error

The condition is unambiguous: if rost is false
The condition is unambiguous: if rost is false
What happens to conditions that are neithertrue nor false? Will they be ignored, or for example the conditionif(op1>cl2 && cl1<cl2) is captured? According to Russian logic this is also "NOT". Unfortunately, the handbook does not explicitly state that (!a) = (a=false).
