Wall Street sheriffs could soon be hunting down fast-moving trading bandits overseas.

Regulatory brass at American exchanges are ready to unleash a new high-tech campaign to isolate and wipe out international high-speed trading “spoofers” who manipulate the US markets from the relative safety of their non-US perches, The Post has learned.

These criminal traders — who gained infamy after accused London spoofer Navinder Singh Sarao, 36, was linked to the 1,000-point “Flash Crash” in 2010 — could send markets crashing and cost US investors millions.

The first regulator to ride the range abroad could be stock exchange operator BATS Global Markets. It is waiting for approval of its Client Suspension Rule, which would give it more firepower to eliminate these electronic gunslingers engaged in dodgy trading that includes spoofing and “layering.”

Approval could come in a matter of weeks, according to trading sources. The New York Stock Exchange and Nasdaq would likely follow the BATS lead and unleash their own international efforts.

The new rule would enable BATS to shut down rogue traders in a matter of weeks, with a regulatory hearing coming within 15 days, rather than today’s longer standard regulatory approach that can take several years.

With layering, unscrupulous traders set “artificial” limit orders to either buy or sell stock. They are rapidly fed into the high-speed electronic markets to move prices in a new direction, often blindsiding naïve traders.

Spoofing is similar except orders are placed and then quickly canceled. The orders fake the market into thinking there is an up or down direction.

The NYSE and Nasdaq had no comment.
