Fast Help needed from experienced developer - fix a failure in existing indicator!

Hello experienced developers,

i have an indicator in place which unfortunately not working correctly. I need an experienced developer who is able to check the code and fix it FAST and RELIABLE. The developer must TEST the indicator before sending me and PROOF that is working correctly. I am making bad experiences that i have to test everything and find common failure after SECONDS. So pls all novice developers also those that didnt understand trading step back, thank you.

Pls CHECK and UNDERSTAND following screenshots. The indicator draws so called Renko Range Boxes into the chart and count them. Principle is clear when you check the screenshots. If you dont understand, pls dont try to get the job. The grey background marks the start and end of counting. As you see the end time is reached before the Renko Range Box ends. The indicator counts till a new Renko Box apperas outside the range. Thats why this Range Box is counted with 4. The indicator has Start / End Date and Start / End Hour inputs. Start / End hour defines the grey background you see in screenshots.

Unfortunately the code has an error. Sometimes, i dont know why, the indicator add Range Box Counts over weekend. Example: On Friday we have just ONE Range Box 1 and on Monday also just ONE. If the setting is to count from Friday till Monday it could be that the result is not TWO Range Box 1, it could be FOUR. Its not always adding two Range Box 1, could be adding six of them or adding a Range Box 2.
