What a converted strategy looks like

Input · ema_cross.pine (Pine Script)
//@version=5
strategy("EMA Cross", overlay=true)

fast = ta.ema(close, 9)
slow = ta.ema(close, 21)

if ta.crossover(fast, slow)
    strategy.entry("Long", strategy.long)
Output · ema_cross.mq5 (MQL5)
#include <Trade\Trade.mqh>
CTrade trade;
int hFast, hSlow;

int OnInit()
{
   hFast = iMA(_Symbol, _Period, 9, 0, MODE_EMA, PRICE_CLOSE);
   hSlow = iMA(_Symbol, _Period, 21, 0, MODE_EMA, PRICE_CLOSE);
   return(INIT_SUCCEEDED);
}

void OnTick()
{
   static datetime lastBar = 0;
   datetime bar = iTime(_Symbol, _Period, 0);
   if(bar == lastBar) return;   // act once per closed bar
   lastBar = bar;

   double fast[], slow[];
   ArraySetAsSeries(fast, true);
   ArraySetAsSeries(slow, true);
   if(CopyBuffer(hFast, 0, 1, 2, fast) < 2) return;
   if(CopyBuffer(hSlow, 0, 1, 2, slow) < 2) return;

   if(fast[1] <= slow[1] && fast[0] > slow[0])   // crossover
      trade.Buy(0.1, _Symbol);
}

This is a static, simplified example and not interactive. To convert your own code, use the converter at the top of this page. Output for your own strategy depends on its logic, so review every result and backtest before trading live.

About CodeFlowOS

CodeFlowOS is a code conversion tool for algorithmic traders who write strategies in Pine Script on TradingView but need them running on MetaTrader 5 or cTrader. Instead of manually rewriting a strategy, you can convert Pine Script to MQL5 or cTrader C#: paste your code, pick a target platform, and get back an Expert Advisor or cBot to review and backtest — no MQL5 or C# experience required.

It's built for retail algo traders, indie strategy developers, and Pine Script coders who want to backtest and deploy their ideas on MT5 or cTrader without hiring a freelancer or spending months learning a new language. Standard indicators like EMA, RSI, MACD, and Bollinger Bands are mapped using a tested, fixed system, so the logic stays consistent across Pine Script, MQL5, and cTrader.

What sets CodeFlowOS apart is its optional platform check: with checks enabled, MetaTrader and cTrader review the translated strategy to help catch issues before testing. Start with the free workflow, then compare plans if the tool fits your needs.
