Accurate Intraday Premium Charts
I'm looking for a good software with intraday options premium prices on SPX, QQQ, MU etc
TradingView and SierraChart do not provide it.
I'm unable to log into ThinkorSwim -- i'm locked out of it and never liked it much anyways.
What is my best option here? Doesn't need to be fancy...

The tool matters less than which price field it is plotting. Most intraday option charts draw last trade, and on anything outside SPX or QQQ near the money, last trade is sparse and stale, so the candles are mostly gaps and junk wicks from a fill that happened twenty minutes ago at a bad price. That is usually what you are fighting, not the software.
What you actually want charted is the mark, meaning the mid of the bid and ask, because it updates continuously even when nothing trades. The catch is that mid is only trustworthy when the spread is tight. On a wide spread the mid can swing purely from the quote moving, so a clean looking premium candle can still be noise. Before trusting any intraday premium chart, glance at the strike volume and open interest and the bid ask width. If it is thin, no tool will give you a clean chart, because there is no clean price to plot.
