I should probably clarify that the pps is unpredictable, the way the GLED algorithm works is identical on every ticker, I suppose it's specifically written for the way Asian stocks trade, and their typical lack of liquidity, so they make their $$$ on the huge spread...rather than the frequency of trading.
That's why I make it a point to never whack to GLED, no matter how frustrated I am in a ticker, their whole point is to pick up bidwhacks as cheaply as possible, then turn around and sell those at the absolute highest possible prices when the inevitable ask slaps do come in. Once you whack to GLED, the system has beaten you as they will sell those at much higher prices at a later date guaranteed. GLED wants your whack's, and will use every trick in the book to get those.
