Is there a way to place a stop order where the stop increases as a function of time or volume? that is to say imagine a channel going up at a 45 degree angle. and you would want to place a sell order if price goes under that diagonal line. Is this possible with sterling trader pro? Or could one use sterling in conjunction with another software that would allow you to actually draw in a diagonal line that would automatically sell if the line is broken as is done with many trade form the chart programs but in this case it would be a diagonal line. I know there are trailing stops but they dont go up as a function of price not time ?
