Here's a breakdown of what this MQL script does, explained in plain language:
This script is designed to automatically place buy and sell orders in the Forex market, aiming to profit from price fluctuations. It's like a mini-robot trader that follows a specific set of rules.
Initialization (Setting the Stage):
-
The script starts by defining several settings that control its behavior. These settings are like knobs and switches that you can adjust.
Royal: This sets a sensitivity level (like a risk tolerance). It determines how likely the script is to place trades based on a random number comparison. A higher number means the script needs a "luckier" random number to trade.SL: This sets the Stop Loss level, in points. This is a safety net. When the trade moves unfavorably by this amount, the trade is automatically closed to limit losses.In_BUYandIn_SELL: These are on/off switches to allow the script to place buy orders (ifIn_BUYis set to true) and sell orders (ifIn_SELLis set to true). If set to false, the robot is no longer allowed to buy/sell
-
It then adjusts some internal variables based on market conditions.
-
It sets the amount of points you'd like to trade
The Trading Logic (The Brain):
-
Time Check: The script only runs once per minute. It prevents itself from running too frequently by remembering the last time it ran and only proceeding if the current time is different.
-
Trade Permission: Before doing anything, it checks if trading is allowed by the broker (e.g., the market isn't closed). If trading is not allowed, it pauses for a bit and tries again later.
-
Order Placement Decision: The heart of the script is a function called
My_Play. It determines whether to place a buy or sell order based on several factors:- Enable/Disable Switch (
flag): TheIn_BUYorIn_SELLsetting (from above) acts as an on/off switch. If it's off, the script won't place trades in that direction (buy or sell). - Heuristic Check (
a1 > a2): This is a simple rule that must be met for the script to trade. The script is evaluating whether to trade a certain way. The script checks a market indicator. If that indicator moves past the current market conditions then it has a higher chance of trading. - Random Number Check (
level > Rand): This is a "luck" factor. The script generates a random number and compares it to theRoyalsetting (represented internally as a level from 2-16422). If the random number is lower than this level, the script proceeds. This adds an element of chance to the trading decisions. - Trade Allowed: It re-checks if trading is allowed.
- Enable/Disable Switch (
-
Order Execution: If all the conditions are met, the script places a buy or sell order in the market.
- It uses a fixed lot size (0.1).
- It sets a stop-loss level (
SL) to limit potential losses. - It sets a take-profit level (
TP) to automatically close the trade when a certain profit is reached.
-
Error Handling: After placing the order, the script checks if the order was successfully placed. If there was an error, it pauses and tries again later.
In Summary:
The script is essentially a very simple trading robot that uses a combination of a market indicator, a luck factor, and user-defined settings to place buy and sell orders. It aims to automate trading while limiting potential losses.
