Hello, I’m Alex and I’m working with Amibroker since 2005. My quote for lower chart (cumulative histogram) is 75AUD, because I’ve done similar indicator long time ago, and I know how to implement it.
As for second chart, my quote is 175AUD, it is more complicated indicator which includes low-level graphics handling in Amibroker.
FYI, my quotes are not including freelancer.com fees, so you should add 10% to them.
BR, Alex
