Last updated: 8 October 2026. Every screenshot below was recorded on 8 October 2026 on an IQ Option Practice account registered in Brazil, on EUR/USD 5-minute candles; the Chart analysis picture in Step 1 was recorded on 5 October 2026. We placed no real-money trade. The settings come from the platform’s dialog and the calculation from the published source code of the platform’s built-in indicators (Quadcode’s script library). The tested box shows what two methods, and the EMA 200 filter that is usually added, did on EUR/USD 5-minute candles recorded between 29 September and 5 October 2026; with so few signals it says nothing about what will happen next.
The Trend Intensity Index (TII) shows what share of the recent price deviation from a moving average was on the upside. It takes the distance of each close from its 60-period simple moving average, adds up the positive distances and the negative distances over the last 30 candles, and plots the positive share as a percentage from 0 to 100. On IQ Option it is one line in a panel under the price chart, with lines at 20, 50 and 80. A reading near 100 means that nearly all of the last 30 closes were above the average, and a reading near 0 that nearly all were below it. On 5-minute EUR/USD candles it was at or above 80 on 31% of the candles and at or below 20 on 47%, so the two methods gave only 19 signals each.
Quick answer
- What it plots: one line from 0 to 100 in a panel under the price chart, with lines at 80 (overbought), 50 and 20 (oversold).
- Formula: TII = 100 × U ÷ (U + D), where U is the sum of the positive deviations of the close from its 60-period SMA over the last 30 candles and D the sum of the sizes of the negative ones.
- Settings on the platform: the major period (60), the minor period (30), the Source (close), Overbought (80) and Oversold (20).
- Reading: above 50 the closes were mostly above the average, below 50 mostly below; the 80 and 20 lines mark the strong-trend areas.
- Where: the Trend list of the Chart analysis panel; search for Trend Intensity.
- Tested: the levels method gave 19 signals and won 42.1% of the decided trades with a 5-minute trade, the middle-line method 19 signals and 61.1% (11 of 18); with the EMA 200 filter each method gave 7 signals. Break-even is 54.1% at an 85% payout, and a few days of one pair prove nothing.
How do you add the Trend Intensity Index on IQ Option?
Set the chart
Choose the asset, the chart type and the candle size first: the indicator is calculated from the candles on the chart. The examples in this guide use 5-minute candles on EUR/USD. These steps use the web traderoom on a Practice balance, and the numbers in each screenshot match the numbers in the text. If you do not have an account yet, see how to register.
Step 1: Open Chart analysis
Click the indicators button (1), the wave icon in the chart toolbar at the bottom left of the chart. The Chart analysis panel opens with the tabs Indicators, Templates, Widgets and Scripts. Stay on Indicators.
Step 2: Find Trend Intensity Index
Type “Trend Intensity” in the Search for indicators box (1), or open the Trend list, and click Trend Intensity Index (2).
Step 3: Check the settings
The dialog has the tabs Basic settings (1), Colors and display and Script. The major period field (2) opens at 60, the length of the simple moving average that the deviation is measured from. The minor period field (3) opens at 30, the number of candles over which the deviations are added. The Source (4) opens at close, the price used. The Overbought (5) opens at 80, the upper level line. The Oversold (6) opens at 20, the lower level line. The first two fields have no short name on the platform: each is labelled with a paragraph of help that says whether it is the major period or the minor period.
Step 4: Check the colours and click Apply
Open the Colors and display tab (1). The tab has a Main line row, red by default, with a colour box and a line-style box, and a Support Lines row with four colour boxes and one line-style box. The four boxes are grey, green, pink and grey by default, in the order of the script’s colours for the 50 line, the 80 line, the 20 line and the shaded band between 80 and 20. All the rows are in box 2. Click Apply (3).
Step 5: Read the panel
The line is drawn in its own panel under the price chart. The title bar of the panel reads Trend Intensity Index (60,30,close), the major period, the minor period and the source, followed by the settings, eye and close icons (1). The scale at the right edge shows 100, 80, 50 and 20; straight lines mark 80 (green), 50 (grey) and 20 (red) and a lighter band fills the space between 80 and 20. The TII is the red line that moves (2).
How is the Trend Intensity Index calculated?
The Quadcode source works in four steps. It takes a simple moving average of the source over the Major Period (60); it subtracts that average from the source on every candle to get the deviation; it adds up the positive deviations over the Minor Period (30) as U and the sizes of the negative deviations over the same candles as D; and it plots 100 × U ÷ (U + D). So the TII is the percentage of the total deviation, over the last 30 candles, that lay above the 60-period average.
| Part | Default | What it does |
|---|---|---|
| TII Major Period | 60 | Length of the simple moving average that the deviation is measured from |
| TII Minor Period | 30 | Number of candles over which the positive and negative deviations are added |
| Source | close | The price used |
| Overbought and Oversold | 80 and 20 | The two level lines; the line at 50 is fixed |
The indicator is credited to M. H. Pee; it rests on the idea that the price keeps going in its previous direction when the trend is strong.
How do you read the Trend Intensity Index?
A TII above 80 or below 20 is read as a strong trend, and a move of the line back towards the middle 50 line as the trend getting weaker. The line is often compared with the RSI and the Stochastic Oscillator, which follow the same principles, and two methods are used. Levels: buy when the line was below 20 and rises above it, and sell when it crosses 80 from above. Middle line: open a long trade when the line crosses 50 from below and a short trade when it drops below 50. The TII gives many false signals, so a trend filter such as an EMA with a period of 200 is recommended.
Because the line is a share of the deviation, it can sit at 0 or 100 for a long time when every close of the last 30 candles is on one side of the average. On those candles it cannot go further, so a level reading says that the trend is established, not how long it will last.
What did it look like on 5-minute candles?
We replayed the library script on EUR/USD 5-minute candles recorded from the Practice traderoom: 1,093 candles from 29 September 2026 (01:55 UTC) to 2 October (20:55 UTC) and 241 from 4 October (21:00 UTC) to 5 October (17:00 UTC). With the defaults the line has a value from the 89th candle of each stretch, 1,158 values in all.
- Range: the line reached both 0 and 100.
- Levels: at or above 80 on 354 candles (31%) and at or below 20 on 547 (47%). On this pair and period the price fell, so the line spent more time low than high.
- Crossings: the 50 line was crossed 19 times, about once every 60 candles, which is much slower than the zero-line crossings of faster oscillators.
Two stills of the platform, window A (the Step 5 picture shows its two ends) and window B (not pictured), agree with the replay: read off the chart at 125 points of the two windows, the line differed from the replay of the script by 0.4 points on average and by 1.4 points at most, on a scale of 0 to 100. In window A, 29 September from 05:27 to 11:16 on the platform clock, the line is at 0 for twenty candles (06:20 to 07:55), rises through 20 at 09:10, through 50 at 09:40 and through 80 at 10:10, makes its high of 93.1 at 10:25 and ends at 82.8 at 11:15. In window B, from 10:44 to 16:33, it starts at 87.9 at 10:45, falls through 80 at 11:20, through 50 at 11:50 and through 20 at 12:10, stays at 0 from 14:05 to 15:10, comes back through 20 at 16:10 and ends at 35.0 at 16:30. (A point is drawn at the close of its candle: the value of the candle that opened at 10:20 sits at the 10:25 mark.)
The two methods, tested
We wrote the two methods as rules on closed candles, with the option opened at the close of the signal candle and settled one candle later, or three. No expiry is given. The levels method has a Higher when the line rises back above 20 and a Lower when it falls back below 80; the middle-line method has a Higher when the line rises above 50 and a Lower when it falls below. We also ran each with the EMA 200 filter: Higher only when the close is above the EMA 200, and Lower only when it is below.
Tested on IQ Option: the Trend Intensity Index, EUR/USD 5-minute candles of 29 September to 5 October 2026
| Asset and candles | EUR/USD binary (regular, not OTC): 1,334 five-minute candles (2026-09-29 01:55 to 2026-10-02 20:55 UTC and 2026-10-04 21:00 to 2026-10-05 17:00 UTC). The candles were recorded from IQ Option’s Practice traderoom. The replay places no orders; it only scores the rule on those closed candles, at an 85% payout. |
|---|---|
| Rule tested | The two methods on closed candles, the option opening at the close of the signal candle. Levels: Higher on the candle where the TII rises back above 20 after being at or below it, Lower where it falls back below 80 after being at or above it. Middle line: Higher where it rises above 50, Lower where it falls below 50. With the EMA 200 filter: Higher only when the close is above the EMA 200, Lower only when it is below. No expiry is given, so the box shows 5 and 15 minutes on 5-minute candles. |
| Signals | Levels 20/80, 5-minute, 1 candle: 19 signals (11 Higher, 8 Lower) Middle line 50, 5-minute, 1 candle: 19 signals (10 Higher, 9 Lower) Levels 20/80 with EMA 200 filter, 5-minute, 1 candle: 7 signals (2 Higher, 5 Lower) Middle line with EMA 200 filter, 5-minute, 1 candle: 7 signals (2 Higher, 5 Lower) Levels 20/80, 5-minute, 3 candles: 19 signals (11 Higher, 8 Lower) Middle line, 5-minute, 3 candles: 19 signals (10 Higher, 9 Lower) |
| Outcomes | Levels 20/80, 5-minute, 1 candle: 8 won, 11 lost, 0 tied; 42.1% of the 19 decided trades won; net −$0.22 per $1 staked at 85% (−$0.20 at 91%) Middle line 50, 5-minute, 1 candle: 11 won, 7 lost, 1 tied; 61.1% of the 18 decided trades won; net +$0.12 per $1 staked at 85% (+$0.16 at 91%) Levels 20/80 with EMA 200 filter, 5-minute, 1 candle: 2 won, 5 lost, 0 tied; 28.6% of the 7 decided trades won; net −$0.47 per $1 staked at 85% (−$0.45 at 91%) Middle line with EMA 200 filter, 5-minute, 1 candle: 4 won, 3 lost, 0 tied; 57.1% of the 7 decided trades won; net +$0.06 per $1 staked at 85% (+$0.09 at 91%) Levels 20/80, 5-minute, 3 candles: 8 won, 11 lost, 0 tied; 42.1% of the 19 decided trades won; net −$0.22 per $1 staked at 85% (−$0.20 at 91%) Middle line, 5-minute, 3 candles: 11 won, 8 lost, 0 tied; 57.9% of the 19 decided trades won; net +$0.07 per $1 staked at 85% (+$0.11 at 91%) |
| Break-even | At an 85% payout a trade needs to win more than 54.1% of its decided trades to break even (1 ÷ 1.85); at 91%, more than 52.4% (1 ÷ 1.91). |
A replay is only a look back at candles recorded on the dates above: it placed no real orders, covers about four and a half days of one pair, and counts overlapping trades as if they were independent. A short test proves nothing about the future, and no profit and no win rate is promised here. IQ Option’s own blog on backtesting says that most strategies need dozens, and often hundreds, of trades before a result means anything.
With a trade of one candle (5 minutes) the levels method gave 19 signals and won 8 of the 19 decided trades (42.1%), and the middle-line method gave 19 signals, won 11, lost 7 and tied 1 (61.1% of the 18 decided). With a trade of three candles (15 minutes) the two figures were 42.1% and 57.9%. The EMA 200 filter left 7 signals for each method: 2 won of 7 (28.6%) for the levels and 4 of 7 (57.1%) for the middle line. Break-even is 54.1% at an 85% payout. The levels method stayed below it in all three cases; the middle-line method stayed above it in all three, but on 7 to 19 trades, and the 95% interval of its highest result runs from 39% to 80%, so none of the six results can be told from chance.
Pros and Cons of the Trend Intensity Index
| Pros | Cons |
|---|---|
| Shows in one number how one-sided the recent closes were around the 60-period average. | Slow: with the defaults it needs 89 candles to start and gave only 19 signals per method in about four and a half days. |
| Bounded between 0 and 100, with level lines, so it reads like the RSI. | It sits at 0 or 100 for long stretches, where it says little. |
| Two simple methods: levels and the middle line. | It gives many false signals and needs a trend filter. |
Common mistakes
- Reading 80 as a sell signal in a strong trend. A value above 80 means a strong trend; the line can stay there.
- Trading too few signals. The two methods gave 19 signals each in our recording, too few to judge.
- Forgetting the warm-up. The line needs 89 candles before its first value.
- Using it alone. A trend filter is recommended, and any rule should be tested on a Practice balance first.

Frequently Asked Questions
Q: What is the Trend Intensity Index?
A: An oscillator from 0 to 100 that shows what share of the deviation of the recent closes from a 60-period moving average was on the upside. It is credited to M. H. Pee.
Q: What settings does the Trend Intensity Index have on IQ Option?
A: Five: the major period (60), the minor period (30), the Source (close), Overbought (80) and Oversold (20); the colours of the line, of the 50, 80 and 20 lines and of the band can be changed on the Colors and display tab.
Q: What do 20, 50 and 80 mean?
A: A TII above 80 or below 20 is read as a strong trend and the 50 line as the middle: above it the closes were mostly above the average, below it mostly below.
Q: Which signals does the TII give?
A: Levels: buy when the line rises back above 20, sell when it falls back below 80. Middle line: buy when it crosses 50 upwards, sell when it crosses downwards. The results of both are in the tested box.
Q: Why does the TII give so few signals?
A: It uses a 60-period average and a 30-candle sum, so the line moves slowly. On 5-minute EUR/USD candles each method gave 19 signals in 1,158 candles.
Q: Can I use the TII on binary options?
A: The platform draws it on any chart. Whether a rule works is something to test on the Practice balance with the expiry you plan to use.
