My DIY forge will almost melt copper but not quite. I'm really at a loss as to why it's not getting hot enough. Any pointers would be great. It uses a forced air propane burner. 2" Kastolite-30 walls, surrounded by 1" of kaowool. The burner enters at an angle so that the flame will "swirl" around the crucible. In this video I had moved the crucible closer to the flame to see if that would make a difference.
I'm trying to fetch 12 months of NBBO bid/ask quote data for each stock in the S&P 500 and holy guacamole, I am getting data at such a slow rate. Based on how long the first one took, it will be four whole days until it is finished fetching. btop says I'm only downloading at 500 KiB/s. Does anybody know a faster way to get this historical data?
try:
req = StockQuotesRequest(
symbol_or_symbols=[symbol]
,
start=start
,
end=end
,
feed=QUOTE_FEED
,
)
return client.get_stock_quotes(req).dftry:
req = StockQuotesRequest(
symbol_or_symbols=[symbol],
start=start,
end=end,
feed=QUOTE_FEED,
)
return client.get_stock_quotes(req).df
My whole data fetching script is about 600 lines because I'm getting some other information as well, but this is the part that I'm using to get the quote data.
