VSA Indicator

MASTERFOREX-V EXCLUSIVE: Welcome! This section is exclusive to visitors from masterforex-v.lt. Here you can find exclusive products and discounted prices, not found on the regular website pages.


Volume spread analysis (VSA) is the first of the three indicators in the VSA package.


  • VSA supply/demand and no-demand/no-supply signals, that point many tops and bottoms in the market. It scans for signals of buying/selling by institutional and professional traders (smart money) or lack of activity in the current timeframe, and on the 2 timeframes above, marking them on the chart. These have an accuracy rate of signaling a market reversal around 75%-80%.
  • Market strength (background) scanner. It scans the trend and the signals to determine if it’s a bullish, bearish or neutral market.
  • Strictly non-repainting indicator: it doesn’t delete, move, or redraw any of the signals it draws. What the user sees in retrospect is what he’d see in real-time, and vice-versa.


Features in detail



Analytical VSA Trader takes signals from the current timeframe, as well of the 2 above timeframes, and presents them in the current timeframe for an easy visualization. The signals VSA draws in the chart are from 3 different timeframes:

  • Current timeframe – drawn as a dot
  • Above timeframe – drawn as a circle
  • 2-Above timeframe – drawn as a square

Each VSA signal has a different color, as shown in the titles below. You can always hover the mouse over the signals in Metatrader, which will show you the description.

Multi-timeframe signals use both the current and the above timeframe to improve accuracy, so they won’t necessarily fit the ones seen in the above timeframes.


Major Supply (Red)/Supply (Violet) and Major Demand (Green)/Demand (Blue) signals

These signals are what determine a trend most of the times – enough of these Major Demand / Demand in a given price area, and the market is said to be going through an accumulation process, which is the smart money flowing into the market, taking long positions. Once this process is done, a sustained trend (bull market) can begin. The inverse process is called distribution. These signals can therefore be more than temporary strength/weakness in the market.


Minor Supply/Minor Demand (Light Blue) signals

They’re similar to the above signals, with the difference being mostly in the volumes – whereas the stronger signals above are accompanied by very high volumes, minor supply / minor demand signals have more modest volumes, but are nonetheless significant. Due to this fact, they usually only signal a temporary turn in the market and hardly have a lasting effect, unless of course, there was significant strength/weakness behind them.


No Demand/No Supply (Brown) signals

While the other signals show the smart money flowing into/out of the market, these show they’re not participating in the market at all. But if market is going up and the big traders aren’t participating, then they must not be interested for some reason! These also signal many market reversals due to that smart money inactivity; when a no-demand is overcame though, that becomes a bullish sign, since it means demand is coming into the market again, and the previous lack of demand was just temporary (vice-verse for no-supply).

VSA Signals


Institutional traders’ market bias can’t usually be seen in just 1 or 2 bars: the market needs to be analyzed in a longer perspective, to determine if they’re accumulating, distributing or buying into dips. And so, the supply and demand signals need to be analyzed together, rather than separately, to determine the bias in the market. . Another important factor to analyze is the trend, because the same signal on a ranging market may have a completely different meaning than in a trending market.

  • This is the main filter to be used when entering in a trade: in most trading setups, for a long trade, the background should be either strong or very strong, or the current timeframe neutral and the above strong/very strong. For short trades, it should be weak/very weak or neutral and weak/very weak in the above timeframe.

The color meaning of background is as follows:

Red – Very weak

Yellow – Weak

Gray – Neutral

Blue – Strong

Green – Very Strong

By default, it looks at 200 bars.



The alerts module aims to alert you only when an important event happens, with a option to send the alerts by email/push notification:

  • Alerts of every VSA signal in the chart
  • Multi-timeframe alerts for Major Supply/Supply and Major Demand/Demand signals: with just 1 chart opened, it can scan all the other timeframes in that symbol for these signals
  • Option to use the background as a filter: if activated, the indicator will only alert you of strong signals if the background is strong, and weak signals if the background is weak
  • Extremely easy to setup: for the standard alerts, you just have to change a single setting
