manual traders are often visual traders........ so the information must be presented visual in some manner...... bar charts, candlestick, heatmaps and so on.....

when using the heat map type approach, my trouble is now i must convert the colors to the represented number......

in the simplest form, 3 colors can suffice....... lime==buy,...... red==sell....... yellow==wait........ easy for me to see....... but kinda need more than that......

if you get much beyond 6 colors, for me it becomes less clear....... matching shades of colors is not my forte.......

if using the segmented led bar graph approach, the colors are visible but also the numbers of lights....... again easy for me........

coding segmented color bars on every symbol on every timeframe to reflect the sum total of dozens of indicators is a quite task......

a cheap way out would be to use the tooltip and include the count.......

consider me cheap.....h

               ObjectSetText(symbol+tfs[k]+"en masse", "ÛÛ",size,"Terminal", clr);
               ObjectSetString(0, symbol+tfs[k]+"en masse", OBJPROP_TOOLTIP, symbol+" en masse >< en masse "+IntegerToString(tfs[k])+" "+IntegerToString(cnt));

metatrader appears to only return integer values correctly up to a certain size........ not sure of that max size, it's very big,...... but at some point the values which should all be positive will be negative and incorrect...... if continuing, the numbers might be positive while still incorrect.......

to get the correct value you must change the integer to a double........ using the decimal format, double class, allows for exponential or scientific expressions......

You can use long instead of int to avoid overflow errors but still use integer values.

not completely sure about this .......

it seems at times when i click on a button, the alert notifying i clicked on it will sound but the intended action will not fulfill.....

other times i must click on the button multiple times before even the alert will sound......

this happens more often when i have to several platforms reduced in size on a single monitor......

i will rush through clicking some button like buy ym, later to notice 1 might not have......

zorder sounds like it might help.....

added OBJPROP_ZORDER to each button........ that property was new to me......

now need to monitor to see if it clears the issue......h

uses tradeexist() function above to alert if new trade will be opposing existing trade, in other words a hedge..... ok or cancel will give the option to proceed or not.....

sometimes i click buy when i meant to click sell.....

if my true intention was to hedge, clicking ok should allow hedge trade.....

usually it is not.....h

most scripts take seconds to run...... like in the blink of an eye.....

some of mine take much longer....... it's the math they are doing..... so long in fact i often wonder if their through........ do i have time to take a nap......

just noticed, in the top right there is a orange symbol with the scripts name..... it remains until the script is done......

guess someone at metaquotes got tired of wondering the same thing......h

linda raschke said she likes to look everyday for what to trade...... that changes......

in the picture above, 6e_h is last.....

this is because in the symbolist it's last......... SymbolName(i,true);
sometimes it's nice to arrange the list to your liking...... even if it's a temporary liking.....

if your trading oil, maybe you want the oils at the top...... or maybe gold at the top..... silver.......

a trend trader might want those symbols that are trending at the top....... a momentum trader might want,,,,,,, on and on.......

this way your not scratchin through a stirred up list in a hurry and only to choose the wrong symbol......

to reorder SymbolName(i,true); , go to the market watch..... click and hold on a symbol then drag it to where you want in the list.....

i imagine linda does something similar..... the top of the her list is what she is trading......

as an example, suppose gold was under a buy alert on multiple higher timeframes and the 1 minute stochastic fell below 5 ......

the idea would be to look for higher timeframe agreements with an extreme opposing stochastic signal on the 1 minute chart......

the 3 dimensional array mentioned above would allow for specific conditions......

taking only the best of the best might increase our odds......h

the idea would be to look for higher timeframe agreements with an extreme opposing stochastic signal on the 1 minute chart......

the 3 dimensional array mentioned above would allow for specific conditions......

MQL5:

            if( (signals[i][2][13] && signals[i][3][13] && signals[i][4][13] && signals[i][5][13] && signals[i][6][13]) && ((signals[i][0][15]) || (signals[i][1][15]) || (signals[i][2][15]) || (!signals[i][0][0]) || (!signals[i][0][4]) || (!signals[i][0][5]) || (!signals[i][0][6]) || (!signals[i][0][7]) ) )              {Alert(symbol+" reversal guassin buy ");}
 
            if( (signals[i][2][14] && signals[i][3][14] && signals[i][4][14] && signals[i][5][14] && signals[i][6][14]) && ((signals[i][0][16]) || (signals[i][1][16]) || (signals[i][2][16]) || ( signals[i][0][0]) || ( signals[i][0][4]) || ( signals[i][0][5]) || ( signals[i][0][6]) || ( signals[i][0][7]) ) )              {Alert(symbol+" reversal guassin sell ");}
            }
 
//-----   darwin array 2 3 2026.mq5 emailed.....  no alerts yet..... might be too restrictive.....
 
 
       }  //------        if(NewBar() || weekend)
 
 
  return rates_total;

uses tradeexist() function above to alert if new trade will be opposing existing trade, in other words a hedge..... ok or cancel will give the option to proceed or not.....

sometimes i click buy when i meant to click sell.....

MQL5:

// need to include counter trend alert..... if(sparam == "Buy YM") { string text= " all clear";

//-----

and sometimes need to be made aware of which account i'm placing the trade in........ as is, have to click ok first...... not good......

added AccountInfoString(ACCOUNT_NAME) at the outset so i know in advance......

still need to add countertrend notification......h

//------

MQL5:

    if(sparam == "Buy ZL_H")
    {
 
    string text= " all clear  "+ AccountInfoString(ACCOUNT_NAME); //   gives me the account name in the yes/no prompt box
 
    if(tradexist("ZL_H",1)) {text = " warning sells exist";}  // idea is to verify hedge....
 
    int BuyZL_H = MessageBox("Buy ZL_H"+text,"0",MB_OKCANCEL);   
 
    if(BuyZL_H != IDOK) return;
 
 
 
    Alert(sparam+ " was pressed  "+ AccountInfoString(ACCOUNT_NAME));
 
    trade.Buy(contracts,"ZL_H",0,0,0,NULL);
 
    }
