When graph settles in for a limited range, making nice sine waves up and down on basically a flat graph, like during Tokyo session this technique forces the graph to pay you profits from the kill zone. Opposing limit orders are placed on each side of the range, with TP's right before the opposing trade gets tagged in. Only one trade is open on the instrument at a time. If range is due for price breakout, just adjust lot size so that when it dips out you can move your TP with it. Small range equals safe trades with quick TP's, lot size should be larger than usual because your only getting a few thousand pips.
