many thanks for choosing SphereTester!
Is the simulator paused when you click/move the buttons and nothing is happening? Please make sure that the chart is moving when you are doing these.
The way SphereTester works is the same as any other indicator or Expert Advisor for Metatrader 4, an action is only taken when a new tick comes in. So if the chart is moving really slowly, let’s say at 1 tick/2 seconds and you click a button right after the last tick, the action associated with that button will only happen when the next tick comes in 2 seconds later. If the chart is paused the action will not happen until it is unpaused and a new tick comes in.
As for the colour of the buttons I might add the option to customise them in a future release.
Please let me know if this helps.
