Pipsgrowth EX16093 Trend

Pipsgrowth EX16093 is not a strategy Expert Advisor. The .mq5 ships without a single OnTick handler, without a single indicator handle, and without any code path that ever submits a market order, places a pending stop, or modifies an open position. What it does is build a fully interactive picture-in-picture sub-chart on top of whichever symbol you load it against — eight named chart objects, five toggle buttons, two editable text fields, and a working OBJ_CHART widget that mirrors a second symbol/timeframe of your choice onto the same window. The tool belongs on the analyst's chart, not on the execution account.

The control surface is anchored by two OBJ_EDIT fields, PIPSymbol and PIPPeriod, drawn in the top-left corner of the host chart. By default they inherit whatever symbol the EA was attached to and whatever period that chart is running on — PIPSetParams() snapshots Symbol() and Period() into curr_symbol and curr_period on OnInit, then PeriodToStr() converts the period enum to its short code ("M5", "H1", "D1", "W1", "MN1") so it can be displayed back to the user. Click the symbol box, type any ticker your broker offers — "EURUSD", "XAUUSD", "US100", "BTCUSD" — and on the OBJECT_ENDEDIT event OnChartEvent reads the new string with ObjectGetString, writes it onto the chart object's OBJPROP_SYMBOL, then re-reads the chart object to confirm the broker accepted the symbol. Whatever you typed gets echoed back into the text field, so a typo is immediately visible. The period field works the same way: type "M15" or "H4" or "240" and OnChartEvent pipes the string through StrToPeriod(), a 30-branch dispatch that maps every textual or numeric code MQL5 understands to its ENUM_TIMEFRAMES constant. If the string does not parse, the function returns false and the previous period is left untouched — there is no error message, the chart simply does not change.

Five OBJ_BUTTON objects sit to the right of the period field, each 18 pixels tall in Arial 10pt on a steel-blue background that matches the text fields. The first two are toggles: PIPDatesButton flips the sub-chart's date axis on and off (the boolean state is read with ObjectGetInteger(OBJPROP_STATE) and written through to OBJPROP_DATE_SCALE), and PIPPricesButton does the same for the price scale. The next two are a zoom pair: PIPPlusButton increments the local scale variable (capped at 5) and pushes it into OBJPROP_CHART_SCALE; PIPMinusButton decrements it (floor 0). Each click also forces the button's own state back to 0 because the state field is only being used as a click counter, not a held state. The fifth button, PIPHideButton, collapses the embedded chart — PIPHideChart() sets the chart's x/y to -1 and both dimensions to 0, effectively moving it off-canvas. A second click restores it: show = 1 - show flips the local flag, and PIPSetParams() runs again with the saved xdist/ydist/xsize/ysize so the sub-chart pops back exactly where it was. The label of the hide button is just an underscore "_" — minimum visual footprint.

All eight objects are created in PIPCreate() during OnInit, parameterised in PIPSetParams(), and removed wholesale by PIPDelete() inside OnDeinit. Sizes are clamped to a minimum of 250x100 in case the user inputs nonsense, and the position is taken straight from the XPosition/YPosition inputs (default 10,10). The control strip is 20 pixels tall; the chart itself is laid out 20 pixels below it, occupying the full XSize x YSize rectangle (default 450x300). The only visual constants you can recolor are TextColor (default clrWhite) and BGColor (default clrSteelBlue) — both feed the OBJPROP_COLOR and OBJPROP_BGCOLOR of every label, button, and edit field so the toolbar reads as a single consistent strip.

Because nothing in the runtime fires on tick, there is no risk model, no order wrapper, no position tracking, and no magic-number discipline to speak of. The InpMagicNumber = 22216093 and InpTradeComment = "Psgrowth.com Expert_16093" inputs are declared in the standard === Identity === group so the file conforms to the EA header schema used across the PipsGrowth catalogue, but they are never read by any function in the .mq5. The three retry helpers TryClose_EX16093, TryClosePartial_EX16093, and TryModify_EX16093 are scaffolded against requote/timeout/price-change conditions the same way as the rest of the catalogue, but they are also never invoked from the runtime — the EA does not place orders, so it has nothing to close, nothing to partially close, and nothing to modify. The #include <Trade\Trade.mqh> import is there only because the retry helpers reference the CTrade class.

Practically, the EA is a multi-timeframe context gadget. Attach it to your trading chart, change the symbol field to the correlated instrument you want to watch (DXY under your EURUSD chart, US10Y under NAS100, gold under silver), and resize the window corner so the sub-chart fills the dead space above your indicators. The period field lets you put a higher-timeframe view inside a lower-timeframe trading chart without alt-tabbing — common workflow: trading on M5 with an H1 context chart embedded, or running a daily bias view inside a 30-minute execution chart. The dates/prices scale toggles and the +/- zoom buttons give you quick visual tuning without leaving the keyboard. The hide button clears the screen instantly when you want to see the underlying chart unobstructed, and restores it with the same dimensions when you click again. Because the EA never opens positions, it can sit on a demo or live account, on a cent account or a prop-firm challenge account, with no risk of accidental execution — and because OnTick is empty, CPU and broker-tick load are effectively zero.
