I want a custom drawing tool for NinjaTrader 8 that lets me create one or more horizontal lines, each in the color and thickness I want, and have that line in my Drawing Tool Tile. Then from the Drawing Tool Tile I can drop whichever horizontal lines I select on any chart, slide each line up or down freely, and have it flash the moment price touches it. The flashing should continue until I tap the space bar. Once a line is created and added to the Drawing Tool Tile, I won't need to change the color or thickness. I need to be able to add as many of these lines as I like from the Drawing Tool Tile and later remove any individual line with a simple right-click context option. No snap-to levels, price labels, or other automatic behaviours. Deliverables • Compiled .zip ready for NinjaTrader’s native import • Fully commented .cs source file (no encryption) • One-page note outlining the key logic, property names, and quick-start instructions Acceptance: after import I can draw multiple lines, watch them flash on touch until space bar is pressed, and remove any line via right-click without affecting any other lines that may be on the chart.
