From 412710eca3940de6265e3e21bfd5c88b42baea68 Mon Sep 17 00:00:00 2001 From: jasonmark10203-prog Date: Tue, 19 Aug 2025 22:13:36 +0300 Subject: [PATCH] Create Trading-app the app should be able to do quick scalping and quick executions in and out of trades together with providing proper risk management that allows proper calculations on what to risk in each trade. The code should work well in the MT5 and should use various strategies to get trades. --- Trading-app | 932 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 932 insertions(+) create mode 100644 Trading-app diff --git a/Trading-app b/Trading-app new file mode 100644 index 0000000..455e0df --- /dev/null +++ b/Trading-app @@ -0,0 +1,932 @@ +//+------------------------------------------------------------------+ +//| SMC_Pro_EA_v3_BALANCED_STRATEGY.mq5 | +//| Copyright 2025, Balanced Trading Strategy | +//| MORE TRADES WITH SMART RISK MANAGEMENT | +//+------------------------------------------------------------------+ +#property copyright "Copyright 2025, Balanced Trading Strategy" +#property link "https://www.mql5.com" +#property version "3.10" +#property description "Balanced strategy - More trades with better risk management" + +#include +#include +#include +#include + +//--- CTrade instances +CTrade trade;
