Your limit does not comply with the stock exchange rules, please adjust your limit. Pay close attention to the decimal places: instead of by 0.01, some shares go up or down by 0.02, 0.05, 0.10, 0.20 or more. You can derive this tick size from the market depth by looking at how the different bid or offer prices are rounded off. To see the market depth, tilt your order screen horizontally; you may need to unlock screen rotation in your device settings.
