VSA No Supply by Mashrab

No Supply Signal created by Mashrab
Hi everyone! This indicator helps you find low-risk entry points during an existing uptrend.
Its main job is to spot "quiet" pauses in a stock's advance, right before it's ready to continue its upward move.
What's the Big Idea?
Think of a stock in an uptrend like someone climbing a staircase. They can't sprint to the top all at once! Eventually, they need to pause, catch their breath, and then continue climbing.
This indicator helps you find that "catch your breath" moment. It looks for a specific signal that shows all the sellers are gone (what we call "No Supply"). When there's no one left to sell, the stock is much more likely to go up.
How It Works (The Signals)
The indicator gives you two simple signals on your chart:
1. The "Get Ready" Signal (Grey Dot)
The indicator is always checking to make sure the stock is in a general uptrend. When it spots a Grey Dot, it's telling you: "Hey, the stock just had a quiet pullback day. Pay attention!"
This dot only appears if the bar meets four conditions:
It's a "down" bar (closed lower than it opened).
It has low volume (this is key! It shows sellers aren't interested).
It has a narrow range (it was a quiet, low-volatility bar).
It closed in the top half of its range (buyers easily stepped in).
When you see a Grey Dot, you don't buy yet. You just add the stock to your watchlist.
2. The "Go" Signal (Blue Triangle)
This is your entry trigger! A Blue Triangle appears on the next bar only if it confirms the upward move. This bar must be:
An "up" bar (closed higher than it opened).
It has high volume (showing that buyers and "big money" are now back and pushing the price up with conviction).
How to Use This Indicator
Grey Dot: See this? The setup looks good. Time to watch this stock.
Blue Triangle: See this? This is your entry confirmation. The move is now "on."
Red Line: This is your safety net. The indicator automatically draws your Stop-Loss at the low of the "Grey Dot" bar. This helps you define your risk on the trade right from the start.
Settings
Uptrend MA Period: (Default: 50) This is just the moving average used to make sure the stock is in an uptrend.
Volume/Range Lookback: (Default: 20) This is how many bars the indicator looks back at to decide what "average" volume or "average" range is.
That's it! I hope this tool helps you find great setups. As always, this isn't a magic crystal ball. It's a tool to help you react to the market. Test it out, and happy trading!
