    Hello.

    Can someone please help me modify this indicator so that it can be used in AutoTrader to open and close trades?
    The indicator works, but I need it to open buy/sell positions when it displays an indication on the screen.
    Also needed only run between certain times of the day as well as position Qty and TS options.

    Thank you.

    See the images for more clarity when to Buy or Sell.

    The script is working – does open/close trades.
    Will it be possible for the script to only open positions when the indicator(grey) is activated. When the indicator draws on the screen and not trade at any other time.
    The earlier attached images shows what I try to say in words when to open positions.

    It uses the same code, so it can only enter when the indicator detects a FVG.ù

    If it doesn’t, please post the name of the instrument traded, timeframe used, date and time of one or more incorrect enrtries.

    @ ROBERTO

    Sorry, but I feel that with all the //  that you’ve placed, this script is only selecting these lines:

    IF High[BI – 1] < Low[BI + 1] THEN              or

    IF High[BI + 1] < Low[BI – 1] THEN

    where, however, B1 is always = 1.      Therefore the lines become:

    IF High[0] < Low[2] THEN       or

    IF High[2] < Low[0] THEN

    Is it right or maybe there should be less //  to filter more variables?

    Yes, those are the only lines that matter in an automated strategy, as he requested to enter whenever a FVG is detected.

    Thank you.

    Somewhere I’m missing something becuse I can’t get yoru suggestion to work.
    My knowledge of any programming code is limited.

    I’m using this on CAC, DAX, DJ, NASDAQ, JAPAN.
    Timeframe – Prefferable 1-5 min
    I’ve seen the existing code runs on any time frame.

    I know it might not be possible to AutoTrade code form this indicator but if this indicator can trigger another acceptable indicator that can trigger auto trade.

    Sorry for the delay.

    Can you please recap when you want to enter either LONG or SHORT based on the code you first posted?

    The script gives indicator on the candle when to Buy/Sell.
    Not a separate script for Long/Short.

    I’ve even asked Ai to write code to give an alarm that will start auto trade.
    Ai wrote two other indicator scripts based on the original script that it will trigger an alert and auto trade to start when the alert is triggered.
    I could not get it to work 100%. Will test it further over the next few days to be sure why it does not work before replying to Ai to modify the scripts.
    I’m sure you will understand the code/scripts better. I struggle to read/understand code -not a strong point of mine.

    What’s the purpose of each one of them?

    Thank you Roberto for the FVG itf. Is it possible to add a line at 50% of the FVG that will disappear when it is reached. Thanks
