The ASI endpoint returns a time series of the NGX All Share Index so you can chart performance, calculate returns over custom periods, or compare the index across date ranges. Each data point includes the closing index value alongside its absolute and percentage change from the prior day. The response also contains period-level statistics (minimum, maximum, and total change) so you can summarise the range without additional computation on your side.
