I want to use indicator for 1 min TF, but option allows only for 5 min and above, manually I tried to change time from 15 min to 1 min in coding but I get error
"The Bigger TF source selected should be greater or equal than the current one"

Also please add histogram for +ve and -ve cross, when market becomes extremly rangebound/sideways it becomes diffiuclt to see and understand crossover

Please help
