Before trying to draw with some conditions in the Start() function, you have to set/initialyze the buffers[].

Code an indicator isn't a simple job. You may have to learn some basics of mql coding.

Wish you all the best in your learning process.

Hello Fellow Programmers,

I have an EA that trades on EURUSD when I attach it to the EURUSD chart. Question is how can I trade multiple pairs without having to attach my EA to multiple charts?

Something like this?

string pairs = "GBPUSD;EURUSD;USDCHF;USDJPY;USDCAD;GBPJPY;EURJPY; GBPCHF;EURAUD;EURCHF;EURGBP;AUDUSD;CHFJPY";

Thanks in advance,

LF

Have your code to trade specific pair when you send your order, it is very simple, right in the documentation.

Use an array instead of a string then loop through the array placing an order for each pair on each iteration. If you haven't used arrays before just look it up in the help file. They're pretty straight forward.

Good luck

Lux

Hello,

first I must apologies because english is not my native language.

How can I modify this EA to tell him to add a position (buy 0.1 lots) at the close of the bar whenever the RSI is over 67, and to sell whenever the RSI is less than 33?
For example:
time close RSI
17:31 1.3855 69.3 ---> buy 0.1
17:32 1.3858 70.5 ---> buy 0.1
17:33 1.3849 66.8 ---> no action
17:34 1.3856 68.4 ---> buy 0.1

Total position +0.03

Same for sell short.

Thank you very much for your help
Panurgo

Hi.

I have a problem. I will code an EA.

When a Profit of 20 PIP of the day is taken so the EA should not open any order until the next day.

Please help me.


Thanks

fxbeginner

An idea would be to not allow trading after the first order of the day. After the ordersend() function, place a "trade = false;"

Then reset the trade allowance each new day:

if(timeprev!=iTime(Symbol(),PERIOD_D1,0)) { //---- This is a new day
timeprev = iTime(Symbol(),PERIOD_D1,0);
trade = true; }

Then when you check your signal:

if(trade) { your trading condition here }

Just an example ...

How do I code an EA to hide all the Buy or Sell Stop Orders from the prying eyes of the Brokers. Current EA has Buy Stops and Sell Stops pending orders.

Thanks

LF

Record the buystop and sellstop value inside the EA, once the price crossover the buystop level, send a buy order, vice versa for sellstop.
