Technical Indicators · Moving Averages

SMAs, EMAs, and the crossover that uses them.

Moving averages are the simplest trend indicator there is, and Vant8 uses three flavours: the simple moving average (SMA) for general smoothing, the exponential moving average (EMA) when recency matters, and the moving-average crossover for explicit entry signals. Same indicator, three jobs.

The two variants

SMA vs EMA — when each one fits

Simple Moving Average (SMA)

A plain average of the last N closing prices. Every bar in the window gets the same weight. The result is smooth but slow — useful when you want a stable baseline that doesn't whip around on a single bar.

Exponential Moving Average (EMA)

A weighted average that gives more weight to recent bars and decays older bars exponentially. Reacts faster to new information. Useful when you want a trend line that tracks the actual move rather than the historical average.

Computation

The math

SMA(period)
= Σ close[i] / period
EMA(period, prev)
= close × (2 / (period + 1)) + prev × (1 − (2 / (period + 1)))
EMA is seeded with the SMA of the first window, then updated bar by bar.
Defaults

The periods we ship

The defaults vary by job. The MA Cross strategy ships with classic fast/slow EMA periods; the Spot Grid AI filter uses the long-haul EMA(200); analytics surfaces SMA(20), SMA(50), and SMA(200).

MA Cross: EMA(5) × EMA(20)

The default fast/slow pair for the crossover strategy. You can tune both, and you can switch from EMA to SMA per strategy.

Trend filter: EMA(200)

The standard long-term trend reference. Spot Grid AI uses this to filter out pairs in steady decline; RSI uses it to qualify counter-trend signals.

Analytics: SMA(20), SMA(50)

Standard short and medium baselines surfaced on portfolio analytics and used as anchors by Mean Reversion.

MA Cross

The crossover signal

The classic moving-average crossover: when the fast MA crosses up through the slow MA, treat it as a trend change to the upside. When it crosses down, treat it as a trend change to the downside. Vant8's MA Cross strategy fires on the close of the crossing bar.

Golden cross

Fast crosses up through slow. The strategy treats it as a long entry on the close of the crossing bar.

Death cross

Fast crosses down through slow. Long exit, or a short entry on perp.

ADX confirmation

MA Cross checks ADX before entering — a crossover with no trend behind it is the textbook whipsaw and we refuse to take it.

Where they show up

Strategies that consume MAs

MA Cross Strategy
Primary entry — long on fast crossing above slow, short / exit on the reverse.
RSI Strategy
Trend filter — refuses counter-trend RSI entries when the long MA slopes against the trade.
Mean Reversion
Baseline — band middle is anchored to an SMA so reversion is relative to the local mean.
Spot Grid AI
Hard filter — uses EMA(200) trend bias to reject pairs in steady decline.
How to read it

Where moving averages can mislead you

Lag is the whole point — and the whole problem

A moving average is, by definition, behind the price. In a fast reversal it gives the signal late. Faster MAs reduce the lag but increase the whipsaw count. There's no parameter that fixes this.

Crossovers fire in ranging markets too

A flat market produces a stream of small crossovers that all lose money. That's why MA Cross on Vant8 always checks ADX before pulling the trigger.
