True SR Level Indicator for MT4 and MT5

True SR Level indicator draws support and resistance levels automatically on the main price chart. It detects peak and bottom levels, can extend lines until breakouts or fixed bar lengths, supports zones, round-number levels, optional ZigZag display, alerts, and EA-ready signal buffers.

The indicator is built for traders who want dynamic support and resistance structure without drawing every level manually. It can show all levels, only upper or lower levels, display level zones, monitor level breaks or approaches, and alert through multiple MetaTrader and external channels.

Key features:

Works in both MetaTrader 4 and MetaTrader 5.
Draws automatic support and resistance levels directly on the main chart.
Detects upper peak levels and lower bottom levels with configurable drawing modes.
Extends levels until selected breakout counts, chart end, fixed bars, or nearest high/low modes.
Optional support and resistance zones with ATR-based or fixed point distance.
Optional round-number levels around the last visible price.
Optional ZigZag display with trend-state coloring.
5 configurable signal slots. Each slot has its own buffer, arrow color, vertical line option, and alert timing.
Signal types include level break, level approach, zone break, zone bounce, round-number break, and trend changed.
Alerts can be sent by popup, push notification, email, sound, Telegram, CSV file, and chart pictogram.
Force refresh and smart HTTP/cache modes help keep visual backtesting and repeated testing faster (more info).
All level styles, zone colors, signal arrows, ZigZag styles, and the show/hide button are controlled from the Inputs tab.

EA and iCustom usage:

The indicator is ready for Expert Advisor integration through iCustom(). Buffers 0-3 are used for visible peak, bottom, and ZigZag data. Buffers 4-8 return the five user-configurable signal slots, so an EA can read only the events you select in the inputs.

For example, Signal 1 can be set to level break, Signal 2 to level approach, Signal 3 to zone bounce, and the EA can read those events from separate buffers. This keeps manual trading, alert trading, and automated trading aligned with the same indicator settings.

Buffer 0: peak point buffer.
Buffer 1: bottom point buffer.
Buffer 2: upper ZigZag helper buffer.
Buffer 3: lower ZigZag helper buffer.
Buffer 4: Signal 1 buffer. Returns 1 or -1 based on the selected Signal 1 setting.
Buffer 5: Signal 2 buffer. Returns 1 or -1 based on the selected Signal 2 setting.
Buffer 6: Signal 3 buffer. Returns 1 or -1 based on the selected Signal 3 setting.
Buffer 7: Signal 4 buffer. Returns 1 or -1 based on the selected Signal 4 setting.
Buffer 8: Signal 5 buffer. Returns 1 or -1 based on the selected Signal 5 setting.

Indicator Inputs

Version: shows the installed indicator version. If support asks for your version, this is the value to check.
Username (without spaces, case sensitive): enter the username you received after purchase. After the first successful activation, you can usually leave it unchanged in other instances (about our ex4 protection).
Auto refresh: controls when server-side level objects are refreshed.
Off disables automatic refresh.
On refreshes when needed after closed bars.
Force refresh also refreshes while you scroll the chart. This is useful during visual backtesting (Example Video).
Smart HTTP request: controls how often the indicator sends calculation requests.
Off requests calculation on every bar. Use this if you want the most direct mode.
Estimate skips requests when the indicator is very likely not to need a new object. This is faster.
Cache saves and reuses previous results for the same symbol, timeframe, and settings. This is usually the fastest for repeated tests.
Cache reset rebuilds the cache for the current symbol, period, and settings.
Redraw timeframe: selects the timeframe used for support and resistance calculation. It can use the current chart timeframe, fixed timeframes, or relative higher timeframe presets.
Allow multiple instances: allows several True SR Level indicators on the same chart by giving each instance its own settings identity.
User notification corner: sets where chart-side status messages are shown.

Level Settings

Extend line: controls how far support and resistance lines are extended:
Don't extend the lines
Extend lines until the 1st breakout through 6th breakout
Extend lines until the chart's end
Extend lines until specified bars
Extend only the nearest high/low lines (0 bar delay)
Extend only the nearest high/low lines (1 bar delay)
Align extended line to MTF mode: aligns extended lines to multi-timeframe mode when MTF calculation is used.
Left fixed extended line length / Right fixed extended line length: set the number of bars used when fixed extension mode is selected.
Show validation candle: marks the candle where a peak or bottom becomes validated.
Drawing mode: selects which price source is used for level detection:
Normal drawing uses candle highs and lows.
Candle body drawing uses candle bodies.
Candle body drawing aligned to MTF mode
Line chart drawing
Line chart drawing aligned to MTF mode
Draw lines in the background: places level objects behind candles and other chart drawings.
Level showing: chooses which levels remain visible:
Show all levels
Show all levels without labels
Show only upper levels
Show only upper levels without labels
Show only lower levels
Show only lower levels without labels

Zones, Round Numbers and ZigZag

ZigZag drawing mode: controls whether the ZigZag is drawn and which price source it uses:
Doesn't draw ZigZag
Normal ZigZag drawing
Candle body ZigZag drawing
Candle body ZigZag drawing aligned to MTF mode
Line chart ZigZag drawing
Line chart ZigZag drawing aligned to MTF mode
Zone drawing mode: controls support and resistance zone width:
Off
ATR based - close range
ATR based - medium range
ATR based - wide range
Fixed distance in points
Fixed zone range in points: sets the zone width when fixed distance mode is selected.
Round numbers step in points: enables round-number levels when greater than 0. A value of 0 turns round-number lines off.
Round numbers start: defines the price-ending offset used for round-number levels.
Number of lines from last visible price: controls the total number of round-number lines drawn around the last visible price.

Signal Settings

Approach distance (in points): sets how close price must come to a level before an approach signal can trigger.
Signal 1 / Signal 2 / Signal 3 / Signal 4 / Signal 5: each signal slot can watch a different event. Each slot has its own iCustom buffer, arrow color, vertical line output, and alert timing. Available events are:
None
Level Break (up/down)
Level Break (counter) - support down / resistance up
Level Break (same) - support up / resistance down
Level Approach (from below/above)
Zone Break (up/down)
Zone Bounce (up/down)
Round Number Break (up/down)
Trend Changed in the past (up/down)
Vertical line on/off and size/style: draws an optional vertical line on signal bars. Use it when you want signals to remain easy to see during chart review.
Arrow on/off and size: draws signal arrows on the main chart. Arrow size can be set to Size 1-8, or turned off.
Arrow distance from candle: controls how far arrows are placed from candles. ATR-based distance adapts to volatility. Point-based distance uses fixed point values.
Up arrow code / Down arrow code: set the Wingdings symbols for bullish/up and bearish/down signal arrows. Defaults are 233 for up and 234 for down.
Signal 1-5 Up color / Signal 1-5 Down color: assign separate bullish and bearish colors to each signal slot. This is useful when several signals are active at the same time.

Alert Settings

Alert when SR lines are redrawn: sends an alert when support or resistance lines are redrawn. This works independently from the five signal slots.
Alert for Signal 1-5: sets alert timing separately for each signal slot:
Off
