Explore the latest free tools from the MQL5 community. Here's a new indicator, expert advisor, or script for MetaTrader.
What it does
- Previous day, previous week and previous month high/low (PDH, PDL, PWH, PWL, PMH, PML), taken from the D1, W1 and MN1 series of the symbol. Lines start at the beginning of the current period and extend to the right.
- Round-number levels: InpRoundCount levels above and below the last close. With InpRoundStep = 0 the step is automatic: 1/100 of the power of ten of the price (EURUSD 1.08 gives 0.01, USDJPY 150 gives 1, a gold price of 4000 gives 10, an index at 20000 gives 100). Or enter your own step in price units.
- Each line has a label: tag, price, T = touches, S = sweeps.
How touches and sweeps are counted (closed bars only)

- A bar touches a level if low <= level + tol and high >= level - tol (inclusive: a bar exactly on the edge of the band counts). Consecutive touching bars count as one touch; a new touch needs at least one bar that did not touch in between.
- A sweep is a bar with high > level + tol and close < level , or low < level - tol and close > level .
- tol = InpTolPoints points, or if that is 0, InpTolATR x ATR( InpATRPeriod ) of the chart timeframe on closed bars.
- Previous day/week/month levels are counted from the start of the current period (day, week or month in broker server time). Round levels are counted over the last InpRoundLookback bars. At most InpMaxScanBars bars are scanned per level.
- Everything is recalculated once per new bar from closed bars; the forming bar is never used.
Alerts
- Sweep alert: the last closed bar swept a level and closed back. Optional touch alert: the last closed bar started a new touch. One evaluation per closed bar; history is not alerted when the indicator is attached.
- Channels: popup, push notification, email, sound file.
Buffers (iCustom)
| Buffer | Content |
|---|---|
| 0-5 | PDH, PDL, PWH, PWL, PMH, PML (price) |
| 6-11 | touch count of the same level |
Read shift 0. The value is calculated at the open of the bar from closed bars only and is not changed afterwards. Older bars keep the values written while they were the current bar, so history from before the indicator was attached is empty ( EMPTY_VALUE ). Plots are DRAW_NONE ; values are visible in the Data Window.
int h = iCustom(_Symbol, PERIOD_M15, "KeyLevelsTouch");
double pdh[1], t[1];
if(CopyBuffer(h, 0, 0, 1, pdh) == 1 && CopyBuffer(h, 6, 0, 1, t) == 1)
Print("PDH ", pdh[0], " touches ", t[0]);
Notes
- Timeframes above H4 are rejected with a message in the Experts tab.
- Higher-timeframe history must be available in the terminal; if it is not loaded yet when the indicator starts, it retries every 2 seconds (also when no ticks arrive, e.g. at the weekend) until the levels can be drawn.
- Round levels are not exposed in buffers (they change with price).
- Objects use the prefix KLT_ and are removed when the indicator is removed.
- Not financial advice. It marks levels and counts past events; it does not predict anything.
Testing
Checked in the Strategy Tester (EURUSD M15, August-October 2026, broker data). On every bar the six previous day / week / month levels and their touch counts, read live at the open of the bar, were compared with an independent rebuild from the raw rates: all 37,416 level values and all 37,416 touch counts matched. Sweep counts and round-number levels are drawn with the same rule but are not exposed in buffers, so they were checked only visually.
