W SMA future b-adj: the back-adjusted weekly averages
W SMA future b-adj is the back-adjusted version of the weekly averages of the main future (W SMA future): the same 20, 50 or 200 weekly closes, but from TradingView's back-adjusted contract series. A 20-week average already spans more than one quarter, so it always contains at least one roll — and the two versions are rarely close. Basics draws the b-adj version as a dotted line in the colour of the normal average, on futures as it is and converted on CFD and index charts. It is off by default.

The main future changes contract every quarter, and the new contract trades at a different price. A weekly average of the future mixes weekly closes of several contracts — a 50-week average spans three or four rolls. There are two ways to deal with that:
| W SMA future | Averages the weekly closes as they traded, each in its own contract. |
|---|---|
| W SMA future b-adj | Averages TradingView's back-adjusted weekly closes: everything before a roll is shifted by the roll gap. This is the average you see when you add a moving average to a back-adjusted weekly chart. |
Because 20 weeks are already more than a quarter, the two versions of every weekly average almost always differ — and the shifts of several rolls add up. On 9 October 2026 the 50-week average of FDAX was 24,765 without adjustment and 25,165 back-adjusted: 400 points apart.
Which one counts?
Both can: traders on a back-adjusted weekly chart see the b-adj value, traders on an unadjusted chart the normal one. In the example above the b-adj line was the level of the day, while the normal average was far away. More on rolls and back-adjusting: back-adjusted levels explained.
How Basics shows them
Each weekly average of the future — 20, 50 and 200 — has its own b-adj checkbox. The b-adj lines appear on every supported chart: on futures (main, mini, micro, nano) as they are, on CFD and index charts converted with the current cash-future difference — exactly like the normal lines.
| Default look | Dotted, in the colour and width of the normal average: W SMA20 black, W SMA50 blue, W SMA200 red |
|---|---|
| Labels on the chart | W SMA20 future b-adj, W SMA50 future b-adj, W SMA200 future b-adj (renamable) |
| Switched on by default | No |
| Value | The average of the last 20, 50 or 200 weekly closes on TradingView's back-adjusted series, with the current price as this week's close |
| Price on your chart | Futures (main, mini, micro, nano): the main future's price as it is. CFD and index charts: converted with the current cash-future difference |
| Where the line is drawn | Today only: one line per average, from the start of today's futures session — no lookback |
| Timeframes | Charts from 1 minute up to the weekly chart, on seconds charts too, unless the level needs more history than the chart loads; not on monthly charts |
| Markets | Nasdaq-100, S&P 500, Dow, Russell 2000, DAX, FTSE 100 and AEX — all tickers |
Why don't I see the lines?
- They are switched off.The b-adj lines are off by default. Check the … b-adj box below each weekly average under Futures SMAs, and the master switch Show all objects in 'Futures SMAs' group in the indicator settings.
- You are looking at an earlier day.A b-adj line is drawn for today only; earlier days keep no b-adj line.
- You are on a timeframe without them.The lines are drawn on charts from 1 minute up to the weekly chart.
- Price is far away from them.Lines are hidden while the level is more than 5 % from the current price, so they don't squeeze the chart. You can change this under General → Level visibility range.
- Your ticker is not recognised.See the supported tickers — and if yours is missing, let me know: requests are very welcome.

Frequently asked questions
What does b-adj mean?
Back-adjusted: calculated on TradingView's back-adjusted contract series, in which older contracts are shifted to the current contract's prices.
Why are the two weekly averages so far apart?
A weekly average spans several quarterly rolls. Every roll gap shifts the older weekly closes in the back-adjusted series, and the shifts add up.
Does the chart's B-ADJ button move the lines?
No. Both versions are fixed values; the button only changes how TradingView draws the candles from before a roll.
Which one should I use?
That is a matter of preference: many futures traders watch the normal average, traders on back-adjusted charts the b-adj one.
Does it work on a CFD or an index chart?
Yes. Like the normal future averages, the b-adj lines are converted with the current cash-future difference.
