Moving Average Screeners

What is a moving-average screener?

A moving-average (MA) screener filters NSE stocks by their relationship to one or more moving averages — price crossing above the 50 EMA, the 20 EMA crossing above the 50, or price holding above the 200-day SMA (the classic long-term-trend filter). The MA is the most-watched technical level on every chart, which is exactly why these crossings act as self-fulfilling triggers: enough traders watch the same lines that breaks above or below them generate real follow-through.

EMA vs SMA vs WMA vs VWAP — when to use which

SMA (Simple Moving Average) takes a flat average of N closes. It's the slowest of the four and the most-respected for long-horizon trend (200-DMA is the textbook bull/bear divider). EMA (Exponential) weights recent closes more heavily, so it turns faster — preferred by swing and intraday traders. WMA (Weighted) is between the two, weighted linearly. VWAP (Volume-Weighted Average Price) resets every day and weights each price tick by the volume traded at that price — it's the intraday anchor used by virtually every institutional desk.

Rule of thumb: use VWAP for intraday entries (above VWAP = institutional support, below = institutional supply), 20 EMA for swing entries, 50 EMA for positional, and 200 SMA for long-term regime. A golden cross (50 above 200) is a slow, statistically meaningful long-term bull signal; a death cross is its inverse.

Why crossovers fail (and how to filter)

In a choppy market, price oscillates around a moving average and produces a stream of false crossover signals — buy, get stopped, sell short, get stopped, repeat. The cure is a trend filter: only trade EMA crossovers when ADX > 25 (the trend is real) or when the higher-timeframe moving average is sloping in the same direction. A 20-EMA-above-50 signal in a market where the 200 EMA is sloping up has roughly 2x the historical follow-through of the same signal in a sloping-down 200 EMA.
