what do you mean with buffer handling? do i get a buffer overflow when i let the script run in an infinite loop?

thanks for the RSI Watchlist. does it update also the not underlying pairs?

thanks a lot!

I'm not sure how to explain this. but I think you don't need to worry about this since you're not drawing a line or histo like most other indicators.

if (MarketInfo(CurrencyPair[i],MODE_BID) > 0 && TimeFrame_Str[i]!="" && RSI_Period[i]>0)
{
PairVerified[i] = true;
}

That's a fail safe check that the code conducts. every currency pair settings should have a valid Currency Pair symbol(), a valid timeframe and an RSI period larger than 0.

I use MarketInfo(CurrencyPair[i],MODE_BID) to try and retrieve the BID of the currency pair provided by the user input. if it returns something larger than 0, that means the symbol given exists in the list that the broker supports. The other 2 values can be compared as is.

The script only display info where all 3 settings of the currency pairs are valid. instead of doing the same checks over and over again, I'll just have it look at the PairVerified[i] value to see if it's true. If it's false, don't process this pair.

This is to prevent user input errors like a symbol typo that'll cause non-stop error messages to be thrown.

a very basic time-based watchlist using script is something like this.

place the blank_window.tpl in the templates folder, place the RSI_Watchlist.mq4 in the SCRIPT folder.

open up any chart, load the template. then attach the script to the chart. click ok after you're done with the settings.

Zen

Yes you can, just add another user inputs for each group called maybe "nickname" or something. then let the label display this as it's text instead.

another question.. is it possible to open chart windows out of an script/EA?

for example the scanners results are EURUSD and CADCHF and now i want the EA/script to open these charts in a separate window automatically?!

thanks.

I have this screener for MT4. The original version you can see:
- Price
- Spread
- Swap
- ATR
- Volume
- RSI
- Stochastic
- ADX
- Pivots
- Moving Average
- Moving Average Cross

I've customized mine to show Standard Deviation (4hr, 50EMA), the Daily 200 Smoothed Moving Average and 4hr 50EMA. You can use the symbols in your Market Watch or customize your own symbols.
