Is this the chip they used to steal money from the Indian stock market until they got banned from India?

They're not banned; their trading restrictions were temporary and have been since lifted, once the allegedly unlawful gains were deposited into escrow, just like SEBI demanded. They simply did not resume trading there even afterwards, for the obvious operational risk reasons.

Their market manipulation is further alleged, not settled. It was also not a high-frequency trading thing, so no, it wouldn't have required anything technically advanced like this either (not that this chip would exist yet anyhow).

It's so tiresome to read asinine comments like this, that are clearly not submitted in earnest. I have a hunch it took me way more effort to investigate your insinuations than you've ever spent thinking about this.
