Digit And Point Normalisation Demo
The single most common bug in beginner MQL4 code is treating "one point" and "one pip" as the same thing. On a 2 or 4 digit broker they are; on a 3 or 5 digit broker, where the quote carries one extra fractional digit, one pip is ten points, and code that hardcodes a stop-loss or take-profit distance in points while a user typed pips ends up ten times too tight or too wide without any error being raised - the order just goes through, quietly wrong. This EA does not trade. It reads every symbol currently selected in Market Watch, and for each one prints its raw Digits and Point value, the pip size derived from them (point multiplied by 10 on a 3 or 5 digit symbol, by 1 otherwise), and a fully worked example: a configurable pip distance converted into points, then into a normalised price offset from the current ask. Because the digit count is read fresh per symbol at runtime rather than assumed, the same table correctly shows a JPY cross at 3 digits, a metal or index at whatever digit count the broker uses, and a standard 5-digit forex pair side by side, without any per-symbol special-casing in the code. Notes and limitations - Only symbols currently selected (visible) in Market Watch are listed; add a symbol there first if it is missing from the table. - This is a display tool - it places no orders and modifies nothing. The pip/point conversion logic shown here is the same pattern used for real order placement elsewhere in this catalogue, on both platforms. - A symbol with no live quote yet (Ask still 0) is skipped from the table rather than shown with a meaningless zero price, on both platforms.
