Please i need help with converting a Ninja indicator into MQL4, MT4. 

Rgds.

 
Afghan123 #:
ok 
Requisition for a code
 
Thanks for the update
 
Pls how can I get my indicator 4
 

Good day coders,

I have developed a MATLAB code for prediction of forex pairs price for next day. Now, I need an expert in mql4 which can read a .csv file: contains date, time, symbol and signal(buy=1, sell=-1 and 0=nothing) with constant SL,TP and LOTS.

I will be appreciated if you provide it for me.

Thanks Maryam.

 
Hello guys! I have one question and I need some help please. I have made a EA based on several indicators for entry/exit/TP/SL etc.  My issue is that it is opening too many trades. What I mean is : I have one 2 lines cross indicator  as one of the conditions for opening a trade. If crossing up + another conditions open buytrade, if crossing down+another conditons opensell. So lets suppose that indicator crossing up, all other conditions are met, the trade is opened. After few candles TP is hit and trade is closed. But the indicator did not flip the other way yet, and then another trade is opened. This is what I want to stop in certain conditions. For example if indicator flipped 7 candles ago , do not open any trade.  What I mean is that for example a trend is forming, all my indicators are agreeing for opening a trade, the trade is opened, and TP is hit after 4-5 candles. And another order is opened but maybe the trend is nearly over, and I am entering close to the bottom. This I want to change. To create a condition in such way that if my indicator flipped [7] candles ago, not to open a trade.
