Trade101 multi-currency indicator

--- 2008.10.24 07:12

Here's the multi-currency turkey. Its task is to order the pairs by the number of pips, relative to the start of the day.

It displays perfectly well when just showing the value of pips. But when I try to display the sequence number in the array, I get a problem.

I have highlighted the place in the code where you can observe this.

In addition to the words, an explanatory picture

The first variant of the indent (from top to bottom, when the line is commented

for ( j=0; j< Max; j++) Price[ j][0]= j; // заменили пункты на порядковый номер |

Second variant, when it remained working

The third variant when the line is left working

// Buf[bar1]=i; // ВОТ ТАК будет строится НОРМАЛЬНО наклонная линия

The variant when the working line is 
Buf[bar1]=15; // THIS IS NOTHING like this

 the same as the second one.

By the way, I noticed that the name of the indicator is not written for the second variant - I have a feeling that there are errors such as division by 0.

And as for the indicator's dependence on 0 bar, it shows up on some timeframes. Sometimes the chart appears - just a horizontal line. But when you shift the chart so that the zero bar is not visible on the screen, it disappears!!!

I do not understand. I would be grateful if someone could point out the problem.

It is necessary to put in an indicator to control the number of bars on the second instrument. And when it changes by more than one, it redraws it completely. It means that there was a history swap.

Nope. Checking on already downloaded history with no internet connection.

Can anyone try to run it in their place?

Put it in a file. I don't want to copy it.

1. If the range is fixed at 14:16, a horizontal line will be drawn. (The range automatically becomes 15:15 and ... everyone goes crazy :), I guess).

For the "original" version, the range is 0:2 and there will also be a line. (This is also what the debug print says).

2. I won't say anything about the sorting algorithm ;). I, in the same situation, preferred 2 arrays and ArraySort

Exactly right. I missed it.

ArraySort is not suitable. You need to sort two dimensions simultaneously. sort the digits and move the indexes at once.

Still, I was right when I gave the link to the T101 system.
