1) Price Tracer need a moving line tracing (connecting) LTP tick movement with respect to the time setting such as START at 0920 or 0945 and end time till 1515 so basically speaking a line from Start Time to End Time showing activity throughout the chart.
being an indicator this should be able to Overlay on the chart just like the other indicators such as EMA etc.
2) ZigZag Movement - Zigzag Indicator based on Price points min 0.1 and max 100 points and a plot line with time setting such as START at 0920 or 0945 and end time till 1515 showing ZigZag movement across as the parameter. for reference please understand the afl in Indicators section of Amibroker as its just a 3 line code.
if interested please connect to me on [email protected] and we can discuss the way forward.
