Problem
The analytics team tracks a metric that fluctuates daily and wants to find the single best window where a buy-low-sell-high strategy would have yielded maximum gain. They need the gain amount and the exact day indices. Write a function that scans a list of daily values and returns the maximum possible profit from one buy and one later sell, along with the buy and sell indices.
