Thank you for the tips - I will try tomorrow morning with the ISLAND exchange settings (before opening the chart I mentioned above) to check if it acquires the data without a glitch. I can't use "TRADES"? because it brings the price?
unadjusted for dividends. See the detta for PCAR (a company that pays dividends):

What is quite scary is how different the prices are from another source (FactSet) - see below. But I will address this later:

The price for ISLAND and SMART (using "ADJUSTED_LAST") is similar (a little scary that it isn't the same, but close enough) for CHTR:

I will post back here re: data acquisition before trying the workaround (once you do it, the code works during the whole day).
Thank you again,
Danilo
