Below are the strategy we need to code for mt4 expert advisor

Please read carefully and ensure that you can do it before applying

The main application we use for our bot is the darvas box as you can see it on the pinscript I gave you. The signal candle operates the same as you see in the script. What we need as modifications are 1. Take profit which I have ask you earlier. Should be a user input for pips value or dollar amount or multipler. 2. User to input his start time and end time for the bot to start scanning for trade. 3. The display of the profit & Loss made whiles the bot takes trade on the upper conner of the chart. To recap on the operations of the bot. You will notice that signal candle is where we set the stop loss. The stop loss we define it as the open of the signal candle. Thus all is there to know about the bot.

So the strategy is coding an mt4 EA where I can see the trades triggered as on the chart? First, I want you to assist me in debugging my current MT4 ETA code as I have attached. 2. I want to have 3 controls 1. Buy Button -- Will be only Long positions 2. Sell Button -- Will be only short positions 3. Buy & Sell -- Will be only for both position 4. Cancel the trade -- Cancel the current trade 3. Only one trade at a time 4. EA should also be visible on chart so that we can do our quality check very well if the trades are correctly executed. 5. Our EA as you will see in the code is based on Darvas Box. Parameter you should be looking is 1. The Buy signal = Breaking the Top 2. The Sell Signal = Breaking the Bottom 3. The Stop Loss = Is put at open of the candle that caused the signal and executed upon the close of candle that breaks it. 4. The Take Profit = Is the input multiplier of the candle that caused the signal. ex. 2x the size of the signal candle. and its executed on the touch of the Take Profit. I have attached also my pinescript of my bot i use to trade on trading view. You can plot it and see its operations. I want trades to be visible as it is on the tradingview chart
