mql4 中有没有一种方法可以逐秒获取价格？

Question

I am a beginner in mql4 and I'm trying something out.

I need to calculate the speed rate of price changes from one second to another. Either on mql4 or pine script. Is there a way to achieve that?

Answer 1

Yes in TradingView, if you have a paid version, you can access the 1 second timeframe and then make your calculation.

Answer 2

it is so easy.just use predifined variable "Ask". Use following codes: {double Price=Ask; Comment("Ask");}

Answer 3

If you want to calculate something, you can do this by

• every Tick = OnTick()
• every x Seconds = OnTimer()

My code down shows the OnTimer() Event every 1 Second.

 //+------------------------------------------------------------------+ //| MQL4 Code | //| | //+------------------------------------------------------------------+ #property strict int OnInit(){ // Timer event for every -1- Second EventSetTimer(1); return(INIT_SUCCEEDED); } void OnDeinit(const int reason){ EventKillTimer(); } void OnTick(){ } void OnTimer(){ // Check every Second new values get_Current_Price(); } void get_Current_Price(){ // MQL Get Current Price. // Get Ask and Bid of the current pair with MarketInfo // and save the values in variables. double PriceAsk = MarketInfo(Symbol(), MODE_ASK); double PriceBid = MarketInfo(Symbol(), MODE_BID); // Print and Comment the values. Print ("Bid = " + DoubleToString(PriceBid, Digits) + " Ask = " + DoubleToString(PriceAsk, Digits)); Comment("Bid = " + DoubleToString(PriceBid, Digits) + " Ask = " + DoubleToString(PriceAsk, Digits)); // MessageBox possible, but will not be the best way //MessageBox("Bid = " + DoubleToString(PriceBid, Digits) + " Ask = " + DoubleToString(PriceAsk, Digits)); // calculate what ever you need }
