At the zero bar the indicator data will not be fixed. It will practically change on every tick, as the zero bar has not yet been formed. Therefore, take data starting from the first bar. If you want to take it from the zero bar, then change PRICE_CLOSE to PRICE_OPEN - this is the only price that does not change on the zero bar, but the indicator will slightly differ from its standard representation - just a little.

It should be understood that this approach cuts off all the current dynamics - all price movements occurring on the current bar will only be "noticed" at the arrival of a new bar.

And false positives - "chattering".

There is always a choice.

Rattling, of course, presents a definite problem. But such a solution is akin to treating a headache by truncating the head.

Can you please tell me why in the Strategy Tester the EA works, but in the demo account, even if I set a small timeframe, the EA just smiles and does not open a position?

Good afternoon all!

Please advise .

PROBLEM

- for real trading in the terminal there are 2 identical charts EUR-USD timeframe - 5 min.

I NEED THAT

- the number of candlesticks in these charts was different (for example - in the graph N1 - 500 bars, the graph N2- 600 bars)

I've deleted candlesticks through the window ARCHIVE QUOTES ..... but they are deleted simultaneously in both charts (I need only one)

Q1. Is it possible to have two identical charts with different number of candlesticks?

Q2 If it is possible to trade on two identical charts with different number of bars, how to format the code.


if (T == true ) // if condition for chart N1 has been fulfilled ( how can we specify that this condition concerns chart N1???)

OrderSend(Symbol(),OP_BUY,0.1,Ask,1,Bid-4710*Point,Bid+300*Point, "jfh",1); // open the order( how do we specify that this order should be opened in the N1 chart ???)

if ( S == true ) // if the condition for chart N2 has been met ( how should we specify that this condition refers to the N2chart ???)

OrderSend(Symbol(),OP_BUY,0.1,Ask,1,Bid-4710*Point,Bid+300*Point, "jfh",1); // open the order ( how do we specify that this order should be opened in the N2 chart???)

Thank you.

 

How can I add price selection to custom indicator? As an example - "Custom Moving Averages", the price in the code is set everywhere Close, although in the standard indicator "Moving Average" you can select a price from the list. This is the same for all indicators with open code from MT4 delivery.

You need to add to the code in this situation. You create an external variable, for example Appled_Price.

And you change all PRICE_CLOSE into Appled_Price in the code.

The Appled_Price values can be within:

Constant Value Description
PRICE_CLOSE 0 Closing price
PRICE_OPEN 1 Opening price
PRICE_HIGH 2 Maximum price
PRICE_LOW 3 Minimum price
PRICE_MEDIAN 4 Average price, (high+low)/2
PRICE_TYPICAL 5 Typical price, (high+low+close)/3
PRICE_WEIGHTED 6 Weighted closing price, (high+low+close+close)/4

Thank you.

Can you explain why you need it? I do not understand the sense of this mystery. Does the profit depend on it?

Ah, yes, sorry, I meant the new builds, and there's a little unusual code.

That's the thing, the code has no free-form price, everything is in arrays, you just can't change it, I've tried it (((

And if it worked, how to make a selection from a drop-down list (like in the picture from my question)?
