We can trade on the last two stocks as they had the largest volume. I will trade it this way by using a naive approach. Please suggest if we can make better entries and exits.

One better approach would be not to take the first long as the previous day high was very close and one could long once PDH was broken.

Looks like comparing 50 day SMA with 5 SMA is not reliable. I compared 30 day SMA with previous day SMA.
