Historic Data for custom symbols

 

I've recently created a calculated custom Dollar index using the major dollar pairs, it is mostly running how I would expect and at the correct price but...

for some reason despite the fact that for each individual currency pair that I have included can be viewed on the monthly chart dating back many years, for the custom index there appears to be only 4 months of data.

on the documentation it mentions that the custom symbols will be calculated to the shortest amount of data so I would understand this if there was the same issue for one of the currency pairs in the index I have created but this doesn't seem to be the case.

I might be missing something or maybe this is normal, If anyone has any idea or could help that would be great.

Thanks, Sam

 

I am afraid you are missing to provide technical details if you need help.

According to your explanation, the problem is in your code as it's your code who creates the custom symbol settings and data.
