This robot analyses price movement and opens orders when the conditions set by the trader are met. Orders are opened with a trailing SL. There are 3 parameters that control order opening:

  1. Trigger: price movement, in full pips, that triggers orders.
  2. Tolerance: max reversal - if the price moves more, the point from which Trigger is calculated is reset to the current price.
  3. Reset Timeout: in seconds - Trigger is reset when timeout reached and order did not open. Set to 0 to disable (not recommended).

Use the In-Panel Form to change the parameters any time.

Example: Trigger = 10, Tolerance = 5, Reset = 120. With these settings the order would be opened if the price moved 10 pips in one direction within 120 seconds. If, during its move the price reversed by more than 5 pips, the Trigger's starting point would be reset and the movement would be observed the next 120 seconds.

When you have set your parameters up, open a trading session by clicking the On/Off Button. After the last order has been opened and you decide to not trade any more, just click the button again and no orders will be made by the robot - current orders would still be handled though (e.g. SL modified).

There can be as many orders opened at a time as you set in Max Trades (up to 5). Orders will not be opened if current Spread > Max Spread - useful if you trade fast-moving markets, e.g. economic news.

If you have set Max Trades > 1, the next trade will be opened when the price has reached current order's (or most recent if there are 2 or more already) Stop-Loss. If you set Wait For Profit to Y, the next order will be opened when the price reaches the point where the next order's Stop-Loss would be at least equal to the current order's Stop-Loss. Look at the Pic 4. 'Wait For Profit'.

Max Cycles determines the method of trading:

  • Unlimited: orders are opened continuously within robot's session;
  • 1 Cycle: There may be only one cycle of Buys or Sells (and you can limit it to only one type with clicking B or S button);
  • 2 Cycles: e.g. one cycle of Buys followed by one cycle of Sells (if the former not in profit).

Close Idle ('I' Button): close order if current price is better than the Order Price but SL still at loss, has not been modified by more than Idle Timeout and the price is getting near to the order price.

If the Jump To Break-Even is on, SL jumps to order price as soon as it can. The J button on the panel controls the parameter.

You can use the X and X ALL buttons to close trades.

Moving the panel: double-click the top part of the panel, then click, hold and drag the panel to another place. Double-click the area again to keep the panel in the new place.


  • If you make any changes to the parameters using the MT 'Inputs' window (F7), Max Cycles, Trigger, Tolerance, both timeouts, S-L Increment, Jump To B-E, Close Idle, Wait For Profit will be reset to their initial values. The robot's session will be turned off, turn it back on if you want the robot to keep trading.
  • For testing the robot in the Strategy Tester, use the 'Visual Mode' if you want check the 'ONLY' Buttons (B, S). The form and all other buttons (except X and X ALL) do not work in S.T. Session is 'On' during test.
  • It is hard to find one set of parameters that would work in all market conditions, therefore the testing usually does not show good results.

This is one of the best robots I have tried at least for my strategy. It outperforms some of the more expensive robots by far.

The only reason I give it 4 (not 5) stars is because its not possible to use it on VPS as it is, and it doesn't support dynamic lots. otherwise its a very handy robot. On day 1 it made money of USDCHF News spike. Its a very versatile EA that can be adjusted to many trading styles and risk approaches.

I will be updating after 1 week again.

Versión 3.1 2020.01.08
Slight correction in the 'Lot Size' functionality: no message displayed after dynamically calculated Lot Size.
Versión 3.0 2019.12.11
1. Added 'Dynamic Lot Size' based on a risk percentage - select Lot Type (fixed or %) and then set Lot Size 0.01-999.99 for 'Fixed Lot' or 0-100 for the 'Risk Percentage Lot'.
2. Value for parameters such as Tolerance, Trigger, SL Increment, SL, TP can be set up to 999 now.
3. Further improvement of the Trigger-Tolerance system for opening new trades.
Versión 2.3 2018.06.11
1. Changed the way of setting the parameters Stop-Loss, Take-Profit, Trigger, Tolerance, S-L Increments: now they can be set up using numeric values instead of a drop-down list - that enables optimization in the Strategy Tester.
2. Improvements made on the 'Only Own Trades' functionality.
Versión 2.2 2017.12.29
Added new parameter 'Only Own Trades' (on customer request): if set to 'yes', the EA can only control (modify, close) orders opened by itself - this is helpful if you use the EA to trade the same pair on two or more timeframes with different settings.
Versión 2.1 2017.11.16
Improved mechanism of opening orders based on Trigger/Tolerance/Reset Time parameters.
Versión 2.0 2017.10.30
'Trailing Mode' added:
Mode 1 - SL follows the price from the moment the order is opened;
Mode 2 - SL starts to follow the price from the moment SL can be moved to the Order Price (Break Even);
Mode 3 - SL follows the price UNTIL it gets to the Order Price (Break Even): from that moment the order can be closed either by Take-Profit (must be set to > 0) or that fixed Stop-Loss. In other words: user gets either profit from Take-Profit or 0 (minus broker commission if applies and/or slippage);
Mode 0 - Trailing Stop is not applied at all (Take-Profit must be > 0).

Trailing Mode is controlled by the 3 small buttons on the right-hand side of the panel, above Session ON/OFF button. Current mode is displayed above the buttons as a number 0 - 3.
